Abstract

The present invention provides methods, systems and equipment for acquiring and extracting information using a biological feature. The method for acquiring information using a biological feature—includes: acquiring first data by a terminal; controlling, by the terminal, a light source to generate an intensity-variable light signal according to the first data, and projecting the intensity-variable light signal on an iris; acquiring, by the terminal, first iris information at least comprising first iris contraction information, in which the first iris contraction information is generated by the iris according to the intensity-variable light signal and comprises a first iris contraction activity; acquiring, by the terminal, second iris information at least comprising second iris contraction information; and extracting, by the terminal, second data from the second iris contraction information according to a preset rule.

First claim

2 . The method according to claim 1 , wherein acquiring by the terminal the first iris information comprises:
acquiring and storing, by the terminal, image information generated by performing an image collection on the first iris contraction activity via an image collecting component.

3 . The method according to claim 1 or 2 , wherein controlling, by the terminal, a light source to generate an intensity-variable light signal according to the first data comprises at least one of:
modulating, by the terminal, the first data on the light source in a preset modulation mode, so as to generate the intensity-variable light signal; and
encoding, by the terminal, the first data to generate an encoded signal of the first data, and modulating the encoded signal on the light source in the preset modulation mode, so as to generate the intensity-variable light signal.

4 . The method according to claim 3 , wherein the preset modulation mode refers to an intensity modulation mode.

5 . The method according to any of claims 1 - 4 , wherein the first data comprises at least one of: a time, a site, a character, order information, trade information, signature data and/or a characteristic value acquired by performing computation on at least one of the time, the site, the character, the order information, the trade information and the signature data.

6 . The method according to any of claims 1 - 5 , wherein acquiring the first data by the terminal comprises at least one of:
generating the first data by the terminal; and receiving, by the terminal, the first data sent by a background server.

7 . The method according to any of claims 1 - 6 , wherein before controlling by the terminal the light source to generate the intensity-variable light signal according to the first data, the method further comprises:
controlling, by the terminal, the light source to generate a reference light signal according to reference data; projecting, by the terminal, the reference light signal on the iris after the terminal controls the light source to generate the reference light signal according to the reference data; and acquiring, by the terminal, reference iris contraction information, in which the reference iris contraction information is generated by the iris according to reference light signal and comprises a reference iris contraction activity.

8 . A method for extracting information using a biological feature, comprising:
receiving, by a background server, first iris information sent by a terminal, wherein the first iris information is acquired by the terminal using the method according to any of claims 1 - 7 ; and extracting, by the background server, the first data from the first iris contraction information according to the preset rule.

9 . The method according to claim 8 , wherein,
the first iris information further comprises: first iris feature information; and the method further comprises: verifying, by the background server, legality of the first iris feature information after the background server receives the first iris feature information sent by the terminal.

10 . The method according to claim 8 or 9 , wherein,
before extracting by the background server the first data from the first iris contraction information according to the preset rule, the method further comprises: receiving, by the background server, the reference iris contraction information sent by the terminal; computing, by the background server, a correspondence between the reference data and the reference iris contraction activity according to the reference data and the reference iris contraction information; and
extracting, by the background server, the first data from the first iris contraction information according to the preset rule comprises: extracting, by the background server, the first data from the first iris contraction information according to the correspondence between the reference data and the reference iris contraction activity.

11 . The method according to claim 10 , wherein the correspondence between the reference data and the reference iris contraction activity comprises a correspondence between the reference data and an activity range of the reference iris contraction activity.

12 . A terminal, comprising:
