The word “module,” as used hereinafter, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language, such as, for example, Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware. It will be appreciated that modules may comprise connected logic units, such as gates and flip-flops, and may comprise programmable units, such as programmable gate arrays or processors. The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable storage medium or other computer storage device. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The recording button 20 can trigger records of one or more iris signal templates. Each of the iris signal templates include an iris signal of an authorized user. The authorized user is able to access a system or an electronic device, such as an electronic device 4. The electronic device 4 is connected to the iris key 2 via the first port 22 of the iris key 2. The first port 22 of the iris key 2 may be a communication (COM) port or a Universal Serial Bus (USB) port. In at least one embodiment, when the recording button 20 is selected, including being pressed or being touched, a record of an iris signal template is triggered. In at least one embodiment, when the record of an iris signal template is triggered, the iris recognition device 24 can recognize an iris signal of an authorized user and record the iris signal to generate the iris signal template.
The input button 21 can trigger an unlocking operation of the electronic device 4. In at least one embodiment, when the input button 21 is selected, including being pressed or being touched, the unlocking operation of the electronic device 4 is triggered, and the iris recognition device 24 can recognize an iris signal of a current user.
In at least one embodiment, the first storage device 23 can include an internal storage system, such as a flash memory, a random access memory (RAM) for temporary storage of information, and/or a read-only memory (ROM) for permanent storage of information. The first storage device 23 can also include an external storage system, such as an external hard disk, a storage card, or a data storage medium.
In at least one embodiment, the first processor 25 can include a central processing unit (CPU), a microprocessor, or other data processing chip that can perform various functions of the iris key 2. The first processor 25 can execute an analog-to-digital conversion to the iris signal recorded by the iris recognition device 24, encrypt the iris signal, then generate the iris signal template using the encrypted iris signal, and store the iris signal template into the first storage device 23.
The iris recognition device 24 can apply mathematical pattern-recognition techniques to images of irises of the user, whose complex random patterns are unique and can be seen from some distance, to recognize the iris signals, and transmit the iris signals to the second processor 45 of the electronic device 4, and/or the first processor 25 of the iris key 2.
The display device 41 can output visible data. The second port 42 may be a COM port, or a USB port, and can be connected to the first port 22 of the iris key 2. The second port 42 can enable communications between the iris key 2 and the electronic device 4.
In at least one embodiment, the second storage device 43 can include an internal storage system, such as a flash memory, a random access memory (RAM) for temporary storage of information, and/or a read-only memory (ROM) for permanent storage of information. The second storage device 43 can also include an external storage system, such as an external hard disk, a storage card, or a data storage medium.
In at least one embodiment, the second processor 45 can include a central processing unit (CPU), a microprocessor, or other data processing chip that can perform various functions of the electronic device 4. The second processor 45 can also execute an analog-to-digital conversion to the iris signal of the authorized users transmitted by the iris key 2, encrypt the iris signal, generate the iris signal template using the encrypted iris signal, and store the iris signal template into the second storage device 4.
The unlocking system 44 can execute an unlocking operation to the electronic device 4 when the input button 21 of the iris key 2 is pressed or touched. In at least one embodiment, the unlocking operation of the electronic device 4 may include turning on or awaking up the electronic device 4.
The signal receiving module 440 can receive an iris signal transmitted from the iris key 2. When the iris key 2 and the electronic device 4 are connected to each other and the input button 21 of the iris key 2 is pressed or touched, the iris recognition device 24 of the iris key 2 can recognize an iris signal of a current user, and transmit the iris signal to the electronic device 4.
The template reading module 441 can read one or more pre-stored iris signal templates from the second storage device 43 of the electronic device 4.
The signal comparison module 442 can compare the received iris signal with the one or more iris signal templates. In at least one embodiment, the signal comparison module 442 can decrypt the one or more iris signal templates, and compare the received iris signal with the decrypted iris signal templates.
The unlocking module 443 can unlock the electronic device 4 when the received iris signal matches with one of the one or more iris signal templates. In at least one embodiment, the unlocking module 443 can turn on or awake up the electronic device 4.
At block 102, a signal receiving module of an electronic device receives an iris signal transmitted from an iris key that is connected to the electronic device. When the iris key and the electronic device are connected to each other and an input button of the iris key is selected, including being pressed or being touched, for example, an iris recognition device of the iris key recognizes an iris signal of a current user, and transmits the iris signal to the electronic device.
