Abstract
An image of an biometric part is used as encryption or decryption key. The biometric part image is obtained, and items within the biometric part are analyzed. Relationships between those parts are determined, e.g. ratios between different parameters of different parts. Those ratios are then used to form the key. A sequence of biometric information can used in which case both the information itself and the sequence are used to form to the key.
Claims22
A biometric analyzing device, comprising:
- a scanning part that scans a biometric part of an individual,
- said scanning part including an image sensor integrated circuit having an active surface which receives radiation and produces an output indicative of an image of the radiation that is received, where said active surface is directly mapped to a user's body part, where the scanning part has pixels which respectively receive a part of the scan of the user's body part, and a size of the active surface is the same as a scanned area of the biometric part, and said pixels are directly mapped to the user's body part to produce information indicative of the scan of the biometric part;
- and
- a computer that analyzes said information in a way that is independent of orientation of the biometric part to create an output indicative of the scan of the biometric part.
1 more element
A system comprising;
- a first scanning part that operates to scan a human body part and obtain scan information indicative of characteristics of said human body part;
- a computer, storing plural files therein,
- said computer running a routine that operates based on said scan information indicative of said body part, to obtain at least one reference within said scan information, and to obtain a digital value based on comparing said scan information of said human body part to said at least one reference by analyzing said scan information along at least one line relative to said at least one reference,
- and said computer using a result of said analyzing to create the digital value indicative of the scan information, where individual bits of the digital value represent whether portions of the scan of the human body part along the line is higher than the reference or lower than the reference.
1 more element
A method comprising;
- scanning a human body part to obtain information indicative of characteristics of said human body part;
- receiving scan information indicative of said scanning into a computer storing plural files;
- said computer operating to obtain at least one reference within said scan information, and to obtain a digital value based on comparing said scan information of said human body part to said at least one reference by analyzing said scan information along at least one line relative to said at least one reference,
- and said computer using a result of said analyzing to create the digital value indicative of the scan information, where individual bits of the digital value represent whether portions of the scan information is higher than the reference or lower than the reference.
