Abstract

The invention relates to a data protection method for a mobile communication device. The method comprises storing first verification information in a hidden area of a storage storing device electrically connected with the mobile communication device, receiving a data packet comprises data privacy instructions and second verification information through a wireless network or a mobile network; determining whether the second verification information obtained from the data packet is identical to the first verification information stored in the hidden area; performing data protection operation on data stored in a storage area if the second verification information obtained from the data packet is identical to the first verification information stored in the hidden area to prevent the data stored in the storage area to be read. By the aid of the method, the data can be protected effectively when the mobile communication device is lost.

Description

technical field [0001] The invention relates to a data protection method, a mobile communication device using the method and a memory storage device thereof. Background technique [0002] With the advancement of mobile communication technology, the functions of smart phones are becoming more and more powerful. Therefore, people are more and more fond of using smart phones to record daily affairs. In particular, the capacity of memory cards used in smart phones is increasing, so that more and more data can be stored. For example, people will use the camera function of a smart phone to take pictures and store the photos in the smart phone for viewing at any time. For another example, people use smart phones to record personal data, such as diaries, travel notes, travel tracks, and the like. [0003] Although smartphones are quite capable of handling personal data, such data may be improperly viewed and distributed if the smartphone is lost. Therefore, how to prevent the le...
