Mobile terminal safety information storage method and system on basis of EMMC (Embedded MultiMedia Card) chip

The invention discloses a mobile terminal safety information storage method and a mobile terminal safety information storage system on the basis of an EMMC (Embedded MultiMedia Card) chip. According to the invention, a key is arranged in a PC (Personal Computer) terminal, and thus, if wanting to modify RPMB (Replay Protected Memory Block) information, a user needs to download the key in the PC terminal by a mobile terminal, so that the safety of related safety information documents in the mobile terminal is greatly improved. The mobile terminal safety information storage method and the mobile terminal safety information storage system on the basis of the EMMC chip are simple and easy to operate and have high practicality.
