Embodiment 1

[0050] This embodiment provides a recovery method for deleted private data, and the method can be applied to a mobile terminal. The mobile terminals include portable mobile terminals such as smart phones, tablet computers, and notebook computers. see figure 1 , which is shown as a flow diagram of a recovery method for deleted private data. Such as figure 1 As shown, the recovery method for deleted privacy data includes the following steps:

[0051] S1. In the mode of enabling data recovery, monitor the deletion operation of the user, and record the original location of the deletion operation object of the deletion operation at the same time. In this embodiment, the privacy data includes that the deletion operation includes deletion of call records, deletion of short messages, deletion of browsing webpages, and deletion of restricted levels. The deletion operation object includes the restriction-level deletion operation object. In this embodiment, the restricted-level dele...

Embodiment 2

[0063] This embodiment provides a recovery system 10 for deleted private data, please refer to figure 2 , is shown as a schematic diagram of the principle structure of the recovery system for deleted private data. Such as figure 2 As shown, the recovery system 10 for deleted private data includes: a monitoring module 101, a recording module 102, a first judgment module 103, an acquisition module 104, a first processing module 105, a database creation module 106, and a second judgment module 107 , a shredding and deleting module 108 , and a second processing module 109 .

[0064] The monitoring module 101 is configured to monitor the user's deletion operation in the mode of enabling data recovery,

[0065] The recording module 102 connected to the monitoring module 101 is used to record the original location of the deletion operation object of the deletion operation. In this embodiment, the privacy data includes that the deletion operation includes deletion of call records...

Embodiment 3

[0072] This embodiment provides a mobile terminal 2, please refer to image 3 , is shown as a schematic diagram of the principle structure of the mobile terminal. Such as image 3 As shown, the mobile terminal 2 includes the recovery system 21 for deleted private data described in Embodiment 2, and an interaction unit 22 connected to the recovery system 21 for deleted private data, and the interaction unit 22 An interactive interface for providing backup and restore operations.

[0073] In summary, the method and system for recovering deleted private data provided by the present invention reconstructs the user's private data, reduces the difficulty of data analysis, effectively improves the efficiency of forensics, and ensures the smooth completion of forensics. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial application value.

Abstract

The invention provides a method for recovering deleted privacy data. The method comprises the steps of monitoring the deletion operation of a user and determining whether the deletion operation belongs to a restricted deletion operation in a data recovery on mode, if so, performing next step, otherwise, monitoring the deletion operation of the user, obtaining a restricted deletion operation object of the restricted deletion operation, performing a first pre-processing manner on the restricted deletion operation object to obtain a unique deletion index value of the restricted deletion operation object, determining whether the restricted deletion operation object needs to perform crushing deletion according to the requirements of a user, and if so, thoroughly grinding the restricted deletion operation object and continuing monitoring, otherwise, performing a second pre-processing manner on the restricted deletion operation object to recover the restricted deletion operation object to a corresponding original position. According to the method, the privacy data of the user are reconstructed, the analysis difficulty of the data is reduced, the evidence efficiency is effectively improved and smooth completion of the evidence collection work is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mobile communication equipment, and relates to a data recovery method and system, in particular to a recovery method and system for deleted private data. Background technique [0002] With the rapid development of mobile Internet of Things, smart phones, and computer technology, traditional industries have fallen into weakness. While smart phones affect our lives, they also save a large number of private information of mobile phone holders, which directly or indirectly reflect the The user behavior that the holder has operated. However, the current research on the security of smart terminal systems mainly focuses on communication security, and there are few studies on information storage and data security on smart terminals. Information related to user behavior, and reconstruct corresponding user behavior, including call behavior between criminals, SMS behavior, web browsing behavior, suspicious deletion...
