Title:
INTERLEAVING AND DEINTERLEAVING METHOD FOR PREVENTING PERIODIC POSITION INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/2006/032186
Kind Code:
A1
Abstract:
A method for implementing volatile cipher key and separate verification module by collecting physical features includes: physical features sensor (11) is set on the handset (10), and control module (30) can be set separately; physical features sensor can collect physical features information of every user in advance, and said physical features can be transmitted to control module (30), and stored in user database (32); after physical features sensor (11) went away said user's body or cipher sent successfully, cipher temporary storage unit (14) reset; when registered user is operating again by using handset (10), control unit (31) can retrieve cipher data in said user database (32), and check whether same records exist or not; if same records exist, control unit (31) give a instruction to lower-stage controlled object (40); if not, control unit (31) delivers a warning information, and store an error record. Thus, potential safety hazard as a result of handset missing can be avoided, and a handset can be shared with multi-user and multi-task, thereby reduces system cost.
