Embodiment Construction

[0020] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0021] see figure 1 As shown, it is the self-test method applied to the Android smart terminal implemented by the present invention. After the program is installed or updated, first all file data of the mobile phone application program is encrypted and backed up, and then entered into the database; the process of the method's power-on self-test includes the following step:

[0022] S1, start;

[0023] S2, obtaining all application programs of the system in the Android mobile phone;

[0024] S3. Querying the database for the name of each application program respectively;

[0025] If the corresponding application program exists in the database, proceed to the next step; if the corresponding application program does not exist in the database, the verification fails, prompting the user, and exiting the program.

Abstract

The invention discloses a self-checking method applied to an Android intelligent-terminal. The method is characterized in that the method includes the following steps: 101, after Android mobile-phoneapplication program installation or updating, encrypting and backing up all file data of mobile-phone application programs, and then sending data into a database; 102, firstly hashing all files of each program in a mobile phone to obtain hashing digests; 103, finding hashing data, which are encrypted through a public key, in the database, and carrying out decryption; and 104, carrying out decryption comparison with previous hashing results, if comparison is inconsistent, determining that the application programs are already modified, and not allowing the same to be opened in a system, and if comparison is consistent, not limiting user use. According to the method, application program self-checking can be realized in real time, cases where the programs are modified are avoided, use of the application programs is enabled to be safer and more reliable, and potential risks brought by use of applications of which data and files are modified are eliminated.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to a system self-inspection method of an Android intelligent terminal. Background technique [0002] Android phone apps are not signed by a trusted source like Apple phone apps, Google uses developer self-signing. Therefore, it is necessary to customize the source code of the framework. After installation, during the self-test, verify the dynamic link library files, Android executable files, and Android package files in each installation directory of the installed application. When the application is running, the Android executable files will change. Before the application is loaded, verify the dynamic link library files, Android executable files, and Android package files in each installation directory of the application. The security requirements of POS machines are relatively high. In order to comply with UnionPay standards, it is necessary to perform application s...
