A security protection method and system for a database under a cloud computing-based Android platform

Abstract

The invention proposes a cloud computing-based android database security protection method and system. A security mechanism of database protection is realized based on a cloud terminal by virtue of a cloud computing technology; and three-layer protection of a database is realized through a user bio-feature identification-based authentication method, an SQL injection protection method and a hybrid encryption algorithm. According to the cloud computing-based android database security protection method and system, the deficiencies of lack of an SQL injection detection mechanism and difficulty in ensuring performance and efficiency in an existing android platform database protection technology are made up for and the security protection is realized based on the cloud terminal, so that the load pressure of a local mobile terminal is effectively reduced, the device performance is ensured, the security protection of the android database is perfecter and more reliable, and the high efficiency and stability of the security protection are ensured.

Description

technical field [0001] The invention relates to the technical field of security protection of databases under the Android platform, in particular to a method and system for security protection of databases under the Android platform based on cloud computing. Background technique [0002] The embedded mobile database SQLite is integrated in the Android system, which stores important private information such as address book, Notes, user configuration, etc. Most of the applications in the Android system will call SQLite to store and process data, so the Android platform database Security is especially important. [0003] At present, most of the research on Android platform security focuses on malicious behavior identification, etc., and there are few studies on its database. Most of the existing research on Android platform database is on its application and performance, while its security research not enough attention. [0004] The existing research on the security of the An...

Problems solved by technology

Among them, the first type mostly uses methods such as data encryption, user passwords, and role-based authority control, and its security mechanisms are mostly implemented locally, which not only increases the memory burden of the local client, but also passwords and passwords are easy to crack, and lack access operations. The mechanism for detecting malicious SQL injection behavior in the database; the second type is realized by means of a WEB server, which reduces the memory burden of the local client and ensures the performance of the local client and the security mechanism, but is not sufficient in terms of security processing efficiency and accuracy.
