摘要
传统的微信数据恢复方法严重依赖于微信应用数据库的主库文件,且恢复效果会因不同手机型号和微信版本产生巨大差别。针对以上问题,提出一种Android系统微信数据的多重融合恢复方法,该方法在深入分析SQLite数据库存储结构的基础上,从微信索引库及其回滚日志文件中提取数据源,并将其与主库数据源进行融合,分别设计索引库恢复算法、索引库回滚日志恢复算法和融合对比去重算法,实现了微信被删除数据的高效恢复。通过实验,微信数据恢复率达到了59.5%,验证了多重融合方法的可行性,通过与传统微信数据恢复方法的对比,恢复率提高了40百分点,明显提高了数据恢复的完整性。
The traditional WeChat data recovery method relies heavily on the main library file of the WeChat application database,and the recovery effect will vary greatly with different phone models and WeChat versions.In view of the above problems,this paper proposes an Android WeChat data fusion of multiple recovery method.On the basis of in-depth analysis of SQLite database storage structure,this method extracted the data source from WeChat index library and rolled back the log file with the main data source integration.It designed the index library recovery algorithm,index library rollback log recovery algorithm and fusion contrast deduplication algorithm respectively,implemented the efficient recovery of deleted WeChat data.Through the experiment,the WeChat data recovery rate reached 59.5%,which verified the feasibility of the multiple fusion method.By comparing with the traditional WeChat data recovery method,the recovery rate is increased by 40%,which significantly improves the integrity of data recovery.
