Embodiment 1

[0129] Thin-film electronic tags have been widely used, but there is no bio-electronic tag generated by the user's body in real time. The fingerprint electronic tag of this embodiment can be attached to a finger to form a biological electronic tag, and the uniqueness of the physical characteristics of the biological electronic tag is achieved by the uniqueness of the user's fingerprint.

[0130] The fingerprint electronic tag of this embodiment is as figure 1 shown, including:

[0131] A flexible film substrate 10;

[0132] An antenna 20 formed by a conductive layer attached to the film substrate 10, the antenna includes a fingerprint area 201, and the fingerprint area 201 forms a fingerprint pattern printed when the fingerprint electronic tag is attached to the finger. Microstrip antenna;

[0133] A protective film 30 covering the antenna and attached to the film substrate; and

[0134] A chip 40 packaged between the film substrate and the protective film and electrically...

Embodiment 2

[0143] The bioelectronic tag or other forms of bioelectronic tags formed based on Embodiment 1 have physiological characteristics corresponding to the user's biological characteristics such as fingerprints. These physical characteristics can be extracted and stored in a certain way, and used for verification of the bioelectronic tag.

[0144] This embodiment relates to a biometric feature extraction method based on bioelectronic tags and corresponding electronic equipment, such as Figure 4 As shown, the method includes:

[0145] Step 110, the electronic device starts the function of the electronic tag reader, and transmits a radio frequency signal;

[0146] It should be noted that the electronic equipment herein (including this embodiment and other embodiments) may include one physical device, and may also include multiple physical devices connected to each other by wire or wirelessly to complete biometric feature extraction. A typical application of this electronic equipmen...

Embodiment 3

[0163] Embodiment 2 After the biometric feature is extracted based on the bioelectronic tag, the extracted biometric feature information can be used to authenticate the user. This embodiment proposes a corresponding bioelectronic tag-based identity verification method and corresponding electronic equipment.

[0164] Such as Figure 6 As shown, the identity verification method based on the bioelectronic tag in this embodiment includes:

[0165] Step 210, the electronic device starts the electronic tag reader function;

[0166] Step 220, the electronic device periodically transmits a radio frequency signal, and detects the response of the bioelectronic tag, which is an electronic tag formed by the human body of the user to be verified in real time; wherein, one cycle includes multiple time slices, On each time slice, use a pair of frequency-power values ​​in the expected user-specific frequency-minimum response power sequence to set the frequency and transmit power of the radi...

Abstract

Methods and devices for achieving spatial positioning of an RFID tag, a 3D signature and man-machine interaction are provided. The method for achieving spatial positioning of an RFID tag comprises the steps of: arranging at least three groups of array antennas which are distributed in a three dimensional form on electronic equipment, wherein each group of array antennas comprises a plurality of antenna array elements extending on one dimension; starting an RFID tag reader to generate a radio frequency electromagnetic field when spatial positioning of the RFID tag is performed; acquiring an induced voltage generated by each antenna array element in each group of array antennas when inducting that there is an RFID tag in the radio frequency electromagnetic field; and determining spatial position information of the RFID tag according to the induced voltage. Based on the method and the device for achieving spatial positioning of the RFID tag, the present invention also provides methods and devices for achieving 3D signature and man-machine interaction. Through adoption of the methods and the devices, the RFID tag can be used for achieving spatial signature, from a planar handwriting to a spatial handwriting, security coefficient of the signature can be improved.

Description

technical field [0001] The present invention relates to an electronic tag and its application, more specifically, to a feature extraction and verification method based on a biological electronic tag, its equipment, and the tag. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification technology, commonly known as electronic tags. RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. Near Field Communication (NFC), also known as short-range wireless communication, is a short-range high-frequency wireless communication ...
