Abstract

The invention discloses a data card and a multi-user access method of an external memory card thereof. The multi-user access method comprises the following steps: when a user visits an external memorizer, the data card searches files to which the user has access in the external memorizer according to identity attribute of the user, and the files are shown to the user; when the fact that the user creates a file in the external memory card or successively uploads a file to the external memory card is detected, the user is prompted to set access permission for the file. The data card and the multi-user access method of the external memory card thereof effectively protect private data of the user.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-user access method for a data card and an external storage card thereof. Background technique [0002] With the increasing popularity of 3G networks, various 3G terminals are gradually favored by people. As a bridge between 3G network and Internet, the data card is naturally favored by consumers. Thanks to the innovation and development of technology, the bandwidth of 3G network has also increased from tens of kbps to tens or even hundreds of Mbps, and the coverage of 3G network has also extended from the city center to the suburbs, so it is possible to surf the Internet anytime and anywhere. [0003] Early data cards only provided network connection functions. With the development of technology and the increase in consumer demand, and with the fierce market competition, more and more functions such as business card holders, short messages, and external memory cards...
