Integrity checking is a technique employed to guarantee that the code and data on a device have not been altered or tampered with in any way that could compromise its security.
Integrity checking in mobile security typically involves verifying the integrity of an application’s code and data and any operating system or other software components running on the device. Integrity checking uses cryptographic algorithms to generate digital signatures or hashes, which are compared against trusted sources’ signatures or hashes.
When signatures or hashes do not match, the code or data has been altered, potentially indicative of a security breach or malware infection. In such cases, the device may be quarantined, and users are advised to take appropriate action to safeguard their data and device. Integrity checking is integral to mobile security, helping guarantee mobile devices’ and applications’ safety and dependability.
