Abstract
The invention is suitable for the field of mobile terminals, and provides a data protection method and a data protection device. The method comprises the following steps of: acquiring face image information of a person facing a mobile terminal-oriented screen, extracting face characteristic data according to the face image information, comparing the face characteristic data with a preset face characteristic data template, and acquiring a data opening right according to the comparative result and a data opening right table; and when different users use the mobile terminal, acquiring face image information, extracting face characteristic data, identifying user identities according to the face characteristic data template, and acquiring a corresponding data opening right to open data. According to the data protection method and the data protection device, different data rights are opened for different users, so that personal data, private data and private authentication data are protected effectively.
Description
technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a data protection method and device. Background technique [0002] Currently, with the popularization of mobile terminals, users can use the mobile terminals to browse information. Various data are stored in the mobile terminal, and relevant authorized network data can also be browsed through the stored various authentication data. Some private or sensitive data is not suitable for friends or strangers to see, especially if the mobile terminal is accidentally lost, which may easily cause personal data leakage. When relatives and friends want to play with mobile terminals, the existing unlocking methods such as passwords or patterns are not friendly enough; the "retrieve the phone" function after the phone is lost also needs to rely on a remote server; how to avoid data in a simple and flexible way Leakage, data management has become an urgent problem to be solved. ...
