As shown in fig. 2, the specific flow of the information acquisition method is as follows:
101. and responding to an information acquisition request carrying the application identifier of the first application, and acquiring the encrypted information corresponding to the application identifier from the information storage directory of the second application.

The encryption information is obtained by fusing first key information of the first application and second key information of the second application and encrypting the first key information and the second key information by using the encryption parameters. The encryption information is preset information and is bound with the application identifier of the first application, and the encryption information can be obtained through a registration request of the first application for the second application after the first application is installed on the terminal.
Specifically, as shown in fig. 3, the encrypted information is obtained as follows:
s1, acquiring a registration request of a first application for a second application.
The registration request may be triggered by a user operating on the first application after the first application is installed, or may be triggered by a user operating on the second application.
S2, acquiring the first key information and the second key information according to the registration request.
The first key information is key information corresponding to the first application package, and the second key information is key information corresponding to the second application package. The first key information may be an MD5 value corresponding to the first application package, an MD4 value, an MD3 value corresponding to the first application package, or a randomly generated character string with a specified number of bits, such as a 64-bit character string. The second key information may be an MD5 value corresponding to the second application package, an MD4 value, an MD3 value corresponding to the second application package, or a randomly generated character string with a specified number of bits, such as a 32-bit character string.
And S3, fusing the first key information and the second key information to obtain information to be encrypted.

For example, the first key information may be an MD5 value corresponding to the first application package, the second key information may be an MD5 value corresponding to the second application package, the MD5 value corresponding to the first application package is a 128-bit character string, and the MD5 value corresponding to the second application package may be a 32-bit character string.

For example, the information to be encrypted is a 64-bit character string, the first encryption parameter is a key, and the 64-bit character string is encrypted by the key to obtain an initial encryption character string. For example, the first encryption parameter is a random character string with a specified digit, the information to be encrypted is a character string with 64 digits, and the initial encryption character string is obtained by fusing the random character string with the specified digit and the character string with 64 digits.
And S5, determining encryption information based on the initial encryption character string.

Specifically, a second encryption parameter is obtained based on the initial encryption character string, and the initial encryption character string and the second encryption parameter are fused to obtain encryption information.
The second encryption parameter may be a key or a random string with a specified number of bits. For example, taking the random character string with the second encryption parameter as the designated digit as an example, the random character string with the designated digit and the initial encryption character string may be directly spliced to obtain the encryption information.
And S6, binding the encrypted information with the application identifier of the first application.
102. And decrypting the encrypted information based on the decryption parameters to obtain decrypted information.
And the decryption parameters are parameters corresponding to the encryption parameters. The decryption parameters may comprise a first decryption parameter, a second decryption parameter. The decryption process for the encrypted information is as follows:
specifically, when the decryption parameter comprises a first decryption parameter, based on the first decryption parameter, a decryption character string meeting a preset condition is screened out from the encrypted information, and an initial decryption character string is obtained; based on the initial decryption string, decryption information is determined.
For example, the first decryption parameter may be a character string with a specified number of bits, such as a character string with 32 bits as the first decryption parameter, specifically, the first decryption parameter may be a first 32-bit character string in the encryption information, the first decryption parameter may be a second 32-bit character string in the encryption information, and the first decryption parameter may be a second 64-bit character string in the encryption information. The preset condition may be a character string with a preset number of bits in the encrypted information, such as a first 32-bit character string in the encrypted information, a first 64-bit character string in the encrypted information, and a second 32-bit character string in the encrypted information. The preset condition corresponds to the first decryption parameter.
For example, the character string in the encrypted message is a 128-bit character string, the first decryption parameter is a last 32-bit character string in the encrypted message, and the preset condition is a first 96-bit character string in the encrypted message. Based on the first decryption parameter, the character string in the encrypted information is cut, the last 32-bit character string in the encrypted information is removed, and the first 96-bit character string in the encrypted information is screened out, so that the initial decryption character string is obtained, namely the initial decryption character string is the first 96-bit character string in the encrypted information.
Specifically, when the decryption parameters further include a second decryption parameter, the initial decryption character string is decrypted according to the second decryption parameter, and initial decryption information is obtained; the initial decryption information is divided to obtain decrypted first key information and decrypted second key information, wherein the first key information is key information corresponding to the first application package, and the second key information is key information corresponding to the second application package; and determining the decrypted first key information and the decrypted second key information as the decrypted information.
The second decryption parameter may be a key, and the key may be a symmetric key or an asymmetric key. For example, the initial decryption string is decrypted by using the key to obtain initial decryption information. Since the initial decryption information may be obtained by fusing the first key information and the second key information, the initial decryption information is divided to obtain the decrypted first key information and the decrypted second key information. The first key information may be an MD5 value corresponding to the first application package, and the second key information may be an MD5 value corresponding to the second application package.
103. The key information contained in the decryption information is verified.
For example, only the first key information may be verified, only the second key information may be verified, the first key information and the second key information may be simultaneously verified, and the first key information and the second key information may also be sequentially verified.
In the embodiment of the application, preferably, the first key information and the second key information are verified in sequence, and specifically, the preset first key information is obtained according to the decrypted first key information; comparing the decrypted first key information with preset first key information; and if the decrypted first key information is different from the preset first key information, the verification result is that the verification is failed.
Specifically, if the decrypted first key information is the same as the preset first key information, acquiring preset second key information; comparing the decrypted second key information with preset second key information; and if the decrypted second key information is the same as the preset second key information, the verification result is that the verification is passed. Therefore, the first key information and the second key information are verified according to the sequence, double verification is achieved substantially, information safety of the second application can be guaranteed, and information leakage is avoided.
In addition, in the embodiment of the present application, the second key information may be verified first, and then the first key information is verified, where the verification process is the same as above, and only the verification order of the first key information and the second key information is different from above.
The preset first key information may be key information generated in a process of registering the first application with the second application, that is, the preset first key information is first key information before encryption. The preset second key information may be key information generated in a process of registering the first application with the second application, that is, the preset second key information is the second key information before encryption.
104. And if the verification is passed, acquiring target information matched with the information acquisition request from the information storage directory of the second application.
The target information can be user information, including information such as a nickname, an account number and a password of a user; the target information may be historical operation information of the user, for example, when the second application is a microblog, the historical operation information of the user may represent a preference of the user for microblog content.
Specifically, after the target information matched with the information acquisition request is acquired, the target information is sent to the first application through the second application.
More specifically, the current time is acquired, and an initial time, which is a time in response to the information acquisition request; and if the difference value between the current time and the initial time is smaller than a preset threshold value, sending the target information to the first application through the second application. Through further time verification, the safety of the information of the second application can be further guaranteed.
The method and the device for acquiring the application identifier of the first application can respond to an information acquisition request carrying the application identifier of the first application, and acquire the encrypted information corresponding to the application identifier from an information storage directory of a second application, wherein the encrypted information is obtained by fusing first key information of the first application and second key information of the second application and encrypting the information by using an encryption parameter; decrypting the encrypted information based on the decryption parameter to obtain decryption information, wherein the decryption parameter is a parameter corresponding to the encryption parameter; verifying the key information contained in the decryption information; and if the verification is passed, acquiring target information matched with the information acquisition request from the information storage directory of the second application. The first application of the embodiment of the application can acquire the information of the second application only through the security authentication, that is, the embodiment of the application decrypts the encrypted information and verifies the key information contained in the decrypted information, so that the first application can acquire the information of the second application, the information of the second application can be prevented from being stolen by the first application, and the information of the second application is prevented from being leaked.
The method described in the above examples is further illustrated in detail below by way of example.
In this embodiment, the information acquisition apparatus is specifically integrated in a computer device, the computer device is an intelligent television, for example, the first application is a user center application, the user center application is an application providing account services for all applications on the intelligent television, and the second application is a third party application on the intelligent television, such as applications of youku, love art, tencent, and the like.
As shown in fig. 4, an information obtaining method specifically includes the following steps:
201. the smart television sends an information acquisition request to the second application through the first application, wherein the information acquisition request carries the application identifier of the first application.
202. And the intelligent television responds to the information acquisition request and acquires the encrypted information corresponding to the application identifier from the information storage directory of the second application.
The smart television can check the application identifier, and if the application identifier is the same as the preset application identifier, the smart television can acquire the encrypted information corresponding to the application identifier from the information storage directory of the second application.
The encryption information is bound with the application identifier of the first application in advance, so that the smart television can obtain the corresponding encryption information according to the application identifier.
The encryption information is obtained by fusing first key information of the first application and second key information of the second application and encrypting the first key information and the second key information by using the encryption parameters.
The encryption process may be: the intelligent television acquires a registration request of a first application for a second application; acquiring first key information and second key information according to the registration request, wherein the first key information is key information corresponding to the first application package, and the second key information is key information corresponding to the second application package; fusing the first key information and the second key information to obtain information to be encrypted; acquiring a first encryption parameter based on the information to be encrypted, and encrypting the information to be encrypted according to the first encryption parameter to obtain an initial encryption character string; acquiring a second encryption parameter based on the initial encryption character string; and fusing the initial encryption character string and the second encryption parameter to obtain encryption information.
For example, the first key information is an MD5 value corresponding to the third-party application package, and the second key information is an MD5 value corresponding to the user-centric application package. The smart television acquires the MD5 value corresponding to the third-party application package and the MD5 value corresponding to the user center application package, and splices the MD5 value corresponding to the third-party application package and the MD5 value corresponding to the user center application package to obtain the information to be encrypted. Then, the smart television acquires a first encryption parameter, wherein the first encryption parameter can be a symmetric key or an asymmetric key, and the smart television encrypts information to be encrypted through the first encryption parameter to acquire an initial encryption character string. And then, the smart television acquires a second encryption parameter, wherein the second encryption parameter can be a character string with a specified number, and the second encryption parameter and the initial encryption character string are spliced to obtain encryption information.
203. And the intelligent television decrypts the encrypted information based on the decryption parameter to obtain the decryption information.
The decryption parameter is a parameter corresponding to the encryption parameter, and the decryption parameter may include a first decryption parameter and a second decryption parameter.
The decryption process may be as follows: screening decryption character strings meeting preset conditions from the encrypted information based on the first decryption parameters to obtain initial decryption character strings; decrypting the initial decryption character string according to the second decryption parameter to obtain initial decryption information; the initial decryption information is divided to obtain decrypted first key information and decrypted second key information, wherein the first key information is key information corresponding to the first application package, and the second key information is key information corresponding to the second application package; and determining the decrypted first key information and the decrypted second key information as the decrypted information.
For example, the first decryption parameter is a string of a specified number of bits, which may be the last 32-bit string in the encrypted information. The second decryption parameter may be a symmetric key or an asymmetric key. And the intelligent television removes the later 32-bit character string in the encrypted information according to the first decryption parameter to obtain an initial decryption character string. After the decryption of the second decryption parameter and the segmentation of the initial decryption information, the first key information obtained by the smart television is the MD5 value corresponding to the third-party application package, and the second key information is the MD5 value corresponding to the user center application package.
204. And the intelligent television verifies the key information contained in the decryption information.
The key information comprises decrypted first key information and decrypted second key information, the first key information is key information corresponding to the first application package, and the second key information is key information corresponding to the second application package.
Specifically, preset first key information is obtained according to the decrypted first key information; comparing the decrypted first key information with preset first key information; if the decrypted first key information is different from the preset first key information, the verification result is that the verification is not passed; if the decrypted first key information is the same as the preset first key information, acquiring preset second key information; comparing the decrypted second key information with preset second key information; and if the decrypted second key information is the same as the preset second key information, the verification result is that the verification is passed.
205. And if the verification is passed, acquiring target information matched with the information acquisition request from the information storage directory of the second application.
