Currently, several common implementation schemes for an Integrated Circuit Card (IC Card) with biometric information collection and identification functions include:
integrated circuit card of one, passive contact type
The card of the integrated circuit card has no built-in battery and gets electricity by inserting receiving equipment; after the card is inserted into the receiving device capable of reading the chip, the card collects the biological characteristic information through the collecting device, and identity authentication is performed by comparing the biological characteristic information. The passive contact type integrated circuit card has the disadvantages that the card needs to be inserted into receiving equipment when identity authentication is carried out, the operation is not simple and convenient enough, and the user experience is not good.
Active non-contact IC card
The card of the integrated circuit card is internally provided with a battery, the integrated circuit card can support hundreds of times of use after being charged once, the card of the integrated circuit card is simultaneously provided with a collection device, and after a power supply is turned on, a user can collect biological characteristic information through the collection device and carry out identity authentication according to the collected biological characteristic information. However, the active contactless ic card has disadvantages in that the card life of the ic card is short, additional charging is required, and the card manufacturing cost is high due to the built-in battery.
Three, passive non-contact integrated circuit card
The card of the integrated circuit card has no built-in battery and gets electricity through the non-contact electromagnetic field of the card swiping terminal; the non-contact passive integrated circuit card is passive and contact-free, is convenient to operate and high in reliability, the biometric identification technology is used for replacing the traditional password input, the safety is improved to a greater extent, and the payment habit of the existing non-contact and biometric identification is also followed.
However, most of the existing passive non-contact integrated circuit cards, especially passive non-contact integrated circuit cards that integrate biometric technology, include two main devices in the card of the integrated circuit card, a control device and a collection device, in the control device, include an interaction unit that performs non-contact connection with the receiving device of the card swiping terminal and an authentication unit that performs biometric information comparison and identity authentication, the power consumption of each device and unit in the card is large when performing identity authentication, the large power consumption can reduce the read-write distance of the card, reduce the stability of the card swiping process, and thus reduce the practicability of the passive non-contact integrated circuit card.
Based on this, the embodiment of the present application provides a method and an apparatus for reducing power consumption, compared with the prior art in which each functional module operates simultaneously, only one device with larger power consumption operates in the same time period, so that on the basis of ensuring the normal operation of the identity authentication function of the passive non-contact integrated circuit card, the power consumption during identity authentication is effectively reduced, thereby improving the read-write distance of the card, improving the stability of the card swiping process, and further improving the practicability of the passive non-contact integrated circuit card. The following is described by way of example.
For the convenience of understanding the present embodiment, a method for reducing power consumption disclosed in the embodiments of the present application will be described in detail first.
Example one
As shown in fig. 1, a method for reducing power consumption according to an embodiment of the present application is described by taking a control device of an integrated circuit card whose execution subject is a passive contactless type as an example, where the method includes:
s101: under the conditions that the target acquisition equipment is in a preset working mode, a preset time interval is reached, and the target acquisition equipment does not finish the work corresponding to the preset working mode, ending the dormant state and generating a collection suspension instruction; the preset working mode is a working mode which consumes more time than a preset time threshold.
Due to the passive non-contact integrated circuit card, in the process of identity authentication, not only the biological characteristic information needs to be continuously collected, but also a connection keeping instruction needs to be sent to the receiving equipment at regular time, so that the data connection with the receiving equipment is kept. Therefore, in the existing passive non-contact type integrated circuit card with the identity authentication function, during the identity authentication process, the target acquisition device needs to be in a normal working mode with large power consumption so as to acquire the biometric information, and the control device needs to be in a normal working mode with large power consumption so as to maintain data connection with the receiving device. At the moment, larger power consumption can be brought, so that the reading and writing distance of the card is reduced, and the stability of the card swiping process is reduced.
Here, the preset operation mode is an operation mode that takes longer than a preset time threshold, for example, the target collection device collects biometric information, the target collection device verifies integrity of the biometric information, and/or the target collection device verifies authenticity of the biometric information. And, the preset time threshold is greater than a preset time interval.
Therefore, the control device is in the dormant state under the condition that the target collection device is in the preset working mode, namely under the condition that the target collection device is in the normal working mode with larger power consumption. Here, the sleep state is an operation state with low frequency and low power consumption. Therefore, under the condition that the target acquisition equipment is in the preset working mode, for example, when the target acquisition equipment acquires the biological characteristic information, only one module of the target acquisition equipment is in the normal working mode with higher power consumption, and the power consumption of the whole passive non-contact integrated circuit card is reduced.
However, if the control device is always in the sleep state when the target acquisition device is in the preset operation mode, the data connection with the receiving device is disconnected, which causes a chain disconnection problem, and therefore, when the target acquisition device does not complete the operation corresponding to the preset operation mode and reaches a predetermined time interval, the control device ends the sleep state and performs communication for maintaining the data connection with the receiving device. At this time, in order to ensure that only one device is in a normal working mode with larger power consumption in the same time period, the control device generates a collection suspension instruction and sends the instruction to the target collection device, so that the target collection device is controlled to stop working. Like this, guaranteed that control device can intermittent type nature and receiving equipment between keep data connection, target collection equipment can intermittently carry out the collection of biological characteristic information, thereby guaranteed that passive non-contact's integrated circuit card can normally carry out authentication work, simultaneously, in same time quantum, only one equipment is in the great normal operating mode of consumption, greatly reduced passive non-contact's integrated circuit card's consumption, when guaranteeing the stability of the flow of punching the card, improved the reading and writing distance of card, improved passive non-contact's integrated circuit card's practicality.
Here, before starting the entire identity authentication process, the control device and the target acquisition device are both in a sleep state to reduce the power consumption of the passive contactless integrated circuit card during the standby process as much as possible. After the control equipment receives a work starting instruction sent by the receiving equipment, for example, after the control equipment receives the work starting instruction sent by a card swiping machine, the control equipment finishes the dormant state and generates an acquisition starting instruction; and then, the control device sends a collection starting instruction to the target collection device so as to enable the target collection device to end the dormant state and start work corresponding to the preset working mode, for example, start collection work of biological characteristic information. And after receiving the state information corresponding to the start of the preset working mode of the target collection device, the control module enters a sleep state. Therefore, only one equipment module is in a normal working mode with larger power consumption in the same time period, and the power consumption of the passive non-contact integrated circuit card is reduced.
S102: and sending the acquisition suspending instruction to the target acquisition equipment so as to enable the target acquisition equipment to stop working corresponding to the preset working mode.
The situation that the control equipment and the target collection equipment work simultaneously can occur inevitably when the control equipment finishes the dormant state and the target collection equipment stops working corresponding to the preset working mode. In order to further reduce the power consumption of the working mode, the control device is enabled to operate in a low-power-consumption working mode after the dormant state is finished and before the target acquisition device stops working corresponding to the preset working mode. The low-power-consumption working mode is a low-frequency working mode.
In order to ensure that the target collection device receives the collection suspending instruction, after the collection suspending instruction is sent to the target collection device, the method further includes: and receiving state information corresponding to the work of the target acquisition equipment in the pause preset working mode.
At this time, the work task of the control device is only to generate and send a collection suspension instruction, and to receive the feedback status information corresponding to the stop of the work in the preset work mode after the target collection device stops the work in the preset work mode, so that the control device is in the low power consumption work mode at this time, for example, when the control device is in the low frequency work mode, the requirement of normal work can be met. And because the control equipment is in a low-power consumption working mode at the moment, the power consumption of the control equipment and the target acquisition equipment during simultaneous working is reduced, and the purpose of reducing the power consumption of the passive non-contact integrated circuit card is also achieved.
S103: and generating and sending a connection maintaining instruction to the receiving device so as to maintain the data connection with the receiving device.
After receiving the state information corresponding to the work of the target acquisition equipment in the pause preset working mode, the control equipment confirms that the work of the target acquisition equipment in the pause preset working mode is already paused, at the moment, the control equipment enters a normal working mode with higher power consumption, and in the normal working mode, a connection maintaining instruction is generated and sent to the receiving equipment so as to maintain the data connection with the receiving equipment.
S104: and generating and sending a collection restarting instruction to the target collection equipment so as to enable the target collection equipment to start work corresponding to the preset working mode.
After the control device completes the data connection with the receiving device, the target acquisition device may be controlled to restart the work corresponding to the preset work mode, for example, the target acquisition device is controlled to restart the acquisition work of the biometric information. Therefore, the working purpose of peak-off working can be achieved in the process of identity authentication, only one device is in a normal working state in the same time period, other devices are in a low-frequency working state under the condition of ensuring normal functions, the requirement that target acquisition equipment acquires biological characteristic information is met, the requirement that control equipment and receiving equipment keep data connection is met, the total system power consumption of the whole passive non-contact integrated circuit card is not greater than a preset power consumption threshold value, and stable working of the passive non-contact integrated circuit card is ensured.
And the control equipment enters a dormant state after receiving the state information corresponding to the start of the work of the preset work mode of the target acquisition equipment. Therefore, only one equipment module is in a normal working mode with larger power consumption in the same time period, and the power consumption of the passive non-contact integrated circuit card is reduced.
At this time, after the restart acquisition instruction is generated and sent to the target acquisition device, before the state information corresponding to the operation of the preset operation mode of the target acquisition device is received, the situation that the control device and the target acquisition device operate simultaneously also inevitably exists. At this time, the control device can be operated in the low power consumption operation mode as well.
And under the condition that the target acquisition equipment finishes the work corresponding to the preset working mode, the control equipment finishes the dormant state and receives the acquired data. And the control equipment compares the received collected data with the stored standard data, sends the comparison result to the receiving equipment and enters a dormant state. Here, the target acquisition device enters a sleep state after completing the work corresponding to the preset work mode. Therefore, only one equipment module is in a normal working mode with larger power consumption in the same time period, the power consumption of the passive non-contact integrated circuit card is reduced, the stability of the card swiping process is ensured, the reading and writing distance of the card is increased, and the practicability of the passive non-contact integrated circuit card is improved.
Example two
As shown in fig. 2, a specific embodiment of the method for reducing power consumption of the present application is given by taking an example in which an execution subject is a passive contactless integrated circuit card and a receiving device is a card swiping terminal, where the passive contactless integrated circuit card in the second embodiment of the present application includes three functional devices: the method for reducing power consumption provided by the second application embodiment specifically comprises the following steps:
s201: and after receiving the starting instruction sent by the card swiping terminal, the control equipment finishes the dormant state, generates and sends a working starting instruction to the authentication equipment.
Before a starting instruction sent by a card swiping terminal is received, the control equipment, the authentication equipment and the target acquisition equipment are all in a dormant state. After receiving a start instruction sent by the card swiping terminal, the control device is firstly awakened from a dormant state to generate a work start instruction, and sends the work start instruction to the authentication device.
S202: and after receiving the work starting instruction of the control equipment, the authentication equipment finishes the dormant state and sends the work starting instruction to the target acquisition equipment.
And after receiving the work starting instruction of the control equipment, the authentication equipment generates state information corresponding to the work starting instruction, and returns the state information corresponding to the work starting instruction to the control equipment. And after receiving the state information corresponding to the received work starting instruction returned by the authentication equipment, the control equipment enters a dormant state.
And after the authentication equipment receives a work starting instruction of the control equipment, the dormant state is ended, and the target acquisition equipment is driven to acquire the biological characteristic information.
S203: and after receiving the work starting instruction, the target acquisition equipment finishes the dormant state, returns the state information corresponding to the work starting instruction to the authentication equipment and starts to acquire the biological characteristic information.
And the authentication equipment enters a dormant state after receiving the state information corresponding to the receiving start working instruction returned by the target acquisition equipment.
The target acquisition equipment continuously acquires the biological characteristic information and authenticates the integrity and authenticity of the biological characteristic information.
S204: when the target acquisition equipment is in a preset working mode, reaches a preset time interval and does not finish the work corresponding to the preset working mode, the control equipment finishes the dormant state, generates and sends a collection suspension instruction to the authentication equipment; the preset working mode is a working mode which consumes more time than a preset time threshold.
And if the time for acquiring the biological characteristic information by the target acquisition equipment is greater than the preset time interval, the target acquisition equipment is considered to be in a preset working mode. And if the target acquisition equipment does not finish the acquisition of the biological characteristic information all the time, the control equipment finishes the dormant state every time a preset time interval is reached along with the increase of the time of the target acquisition equipment in the preset working mode, and generates and sends an acquisition suspension instruction to the authentication equipment.
S205: and the authentication equipment receives the acquisition suspending instruction, finishes the dormant state and sends the acquisition suspending instruction to the target acquisition equipment.
S206: the control device generates and sends a connection keeping instruction to the card swiping terminal so as to keep data connection with the card swiping terminal.
The control device determines whether the target collection device receives the collection suspension instruction, so as to determine whether the target collection device stops the work corresponding to the preset working mode, for example, the collection work of the biological characteristic information is stopped, and determine whether the control device should start the data connection work with the card swiping device. Therefore, the authentication device needs to send the state information corresponding to the acquisition suspending instruction to the control device after receiving the state information corresponding to the acquisition suspending instruction sent by the target acquisition device, and then re-enters the hibernation state.
The situation that the control equipment, the authentication equipment and the target collection equipment work simultaneously cannot be avoided because the control equipment finishes the dormant state and the target collection equipment stops working corresponding to the preset working mode. In order to further reduce the power consumption of the working mode, after the sleep state is ended, before the target acquisition device stops working corresponding to the preset working mode, the control device and/or the authentication device is/are operated in a low-power-consumption working mode. The low-power-consumption working mode is a low-frequency working mode.
And after the control equipment receives the state information corresponding to the acquisition suspension receiving instruction sent by the authentication equipment, the control equipment confirms that the target acquisition equipment stops working corresponding to the preset working mode and enters a dormant state. At this time, the control device generates and transmits a connection keeping instruction to the card swiping terminal to keep the data connection with the card swiping terminal.
In the specific implementation process, the control device needs to perform a wait Time delay request (WTX) command interaction with the card swiping terminal at regular Time, so that at this Time, the control device sends a WTX request to the card swiping terminal and receives a WTX response returned by the card swiping terminal.
S207: and generating and sending a collection restarting instruction to the authentication equipment.
S208: and after receiving the collection restarting instruction, the authentication equipment finishes the dormant state and sends the collection restarting instruction to the target collection equipment so as to enable the target collection equipment to start the work corresponding to the preset working mode.
The control device determines whether the target collection device receives a restart collection instruction, so as to determine whether the target collection device restarts the work corresponding to the preset working mode, for example, the collection work of the biological characteristic information, and the target collection device can enter the sleep mode after the target collection device is determined to restart the work corresponding to the preset working mode. Therefore, the authentication device needs to send the state information corresponding to the restart acquisition instruction to the control device after receiving the state information corresponding to the restart acquisition instruction sent by the target acquisition device, and then re-enters the hibernation state.
Here, the control device enters the hibernation state after receiving the state information corresponding to the collection restart instruction sent by the authentication device. At this time, the target acquisition device starts the operation corresponding to the preset operation mode, for example, starts the acquisition operation of the biometric information.
After the target collection device restarts the work corresponding to the preset work mode, the situation that the control device, the authentication device and the target collection device work simultaneously inevitably occurs before the control module receives the state information corresponding to the restart collection instruction. In order to further reduce the power consumption of the working mode, after the target acquisition device restarts the work corresponding to the preset working mode and before the control module receives the state information corresponding to the acquisition restart instruction, the control device and/or the authentication device is operated in the low power consumption working mode. The low-power-consumption working mode is a low-frequency working mode.
S209: and after the target acquisition equipment acquires the biological characteristic information meeting the preset requirement, sending the biological characteristic information meeting the preset requirement to the authentication equipment, and entering a dormant state.
S210: and the authentication equipment receives the biological characteristic information which is sent by the target acquisition equipment and meets the preset requirement, finishes the dormant state and performs identity authentication.
And after the authentication equipment finishes the dormant state, performing identity authentication according to the biological characteristic information meeting the preset requirement to generate an identity authentication result, and sending the identity authentication result to the control equipment. And after the identity authentication result is sent to the control equipment, the authentication equipment enters the dormant state again.
S211: and after the control equipment receives the identity authentication result sent by the authentication equipment, the control equipment finishes the dormant state and generates response information according to the identity authentication result.
And after receiving the identity authentication result sent by the authentication equipment, the control equipment finishes the dormant state, generates response information according to the identity authentication result and sends the response information to the card swiping terminal. And after the response information is sent to the card swiping terminal, the control equipment enters the dormant state again.
In the second embodiment of the present application:
the control device may be: a Security Element (SE), a Micro Controller Unit (MCU), or any electronic device capable of implementing a control function.
The authentication device may be: and any electronic device capable of realizing an authentication function, such as a Microcontroller Unit (MCU).
The target acquisition device may be: any electronic equipment capable of realizing the acquisition function, such as a Sensor and the like.
