Abstract

This invention provides a system and a method for detecting and deactivating an illegal access control card. A card swiping frequency field of the access control card is detected and read with an access control machine, such that a numerical value of the card swiping frequency field of the access control card is accumulated by the access control machine and is then rewritten and stored into the card swiping frequency field of the access control card, and then, an updated numerical value of the card swiping frequency field contained in card swiping information of the access control card is returned to an access control management module by the access control machine so as to be saved, whereby the access control management module can check whether the numerical value of the card swiping frequency field of the data and the numerical value of the card swiping frequency field of former card swiping data are regularly accumulated or not so as to judge whether the access control card is copied and is blacklisted or not, and the access control machine rewrites and deletes an identification information field of a blacklist card when the blacklist card is reused, so that the card cannot be used.

Description

   System and method for detecting and deactivating illegal access control cards   

The present invention is an access control card, in particular, a system and method for detecting and deactivating an illegal access control card by using logic of checking the field value of the number of card swipes of the data and the value field of the previous card swipes.

At present, access control card anti-counterfeiting technology is mostly developed in the direction of encryption and decryption to read card content, multiple authentication or access control card entities plus anti-counterfeiting materials, but there is no defense mechanism for illegal access control cards. In addition, the historical identification method may be used to analyze the repetition of the item identification code, but it cannot be applied to the situation where the access card is repeatedly sensed at the same access point.

In the prior art, suspicious counterfeit access control cards are detected using behavior model training and sensing path analysis. However, this method needs to be confirmed by the user before it can be judged that there is a copy / counterfeit card. It will obviously cause confusion for users who often have access to different locations and access control points with unstable trajectories.

It can be seen that the above-mentioned conventional methods still have poor system availability, which is not a convenient and easy-to-use design that needs to be improved.

In view of the various shortcomings derived from the above-mentioned conventional methods, the inventor of this case has been eager to improve and innovate. After years of painstaking research, he finally successfully developed the system and method for detecting and deactivating illegal access control cards.

The invention provides a system for detecting and deactivating an illegal access control card, which mainly includes an access control card, an access control machine, and an access control management module. The access control card further includes an identification information column and a card swipe number column. The access control machine also includes a card information reading module that reads the identification information column of the access card and the number of swipes. The blacklist comparison module compares the identification information column with the card blacklist. The field write-back module reads the card. The number of times is written into the number of times of swiping card, and the upload module will identify the information column and the number of times of swiping card. The access control management module also includes a blacklist generation module, which generates a card blacklist, stores the card blacklist in the database, and uses the blacklist download module to download the card blacklist to the blacklist comparison module, and the abnormality detection module. It compares the identification information column of the access card and the number of swipes.

The invention provides a method for detecting and deactivating an illegal access control card. The steps include: the access control machine uses a card information reading module to read the identification information column of the access control card and the number of swipes; the blacklist comparison mode of the access control machine The system compares the identification information column and the card blacklist. If the identification information column matches the card blacklist, the field writeback module deletes the content of the identification information column. If the identification information column does not match the card blacklist, the field is written back to the template. The group writes the number of card swipes into the card swipe column and opens the door; and the upload module of the access control machine uploads the identification information column, card swipe column and card swipe time of the access card to the database of the access control management module for storage.

The access control management module reads the records of the corresponding number of times of swiping in the database with the same identification information column. The anomaly detection module compares the values of the number of times of swiping before and after the card according to the order of the time of swiping; and if If the number of digits in the number of times before and after the card is accumulated regularly, the access control card is judged to be normal; if the number of digits in the number of times in the field before and after the card is irregularly accumulated, the access card is judged to be illegal. A blacklist generation module is generated. The card blacklist is downloaded to the access control machine by the blacklist download module.

The difference between the present invention and the prior art lies in that the present invention utilizes the reading and writing technology of the number-of-swipe field of the access control machine and the card, and the access control management module checks the value of the number-of-swipe field and the number of times of swiping the card Whether the digit value accumulates regularly, and then accurately determine whether a copy / counterfeit card is in use, and then add it to the blacklist. When the blacklist card is swiped again, the access control will immediately delete the content of its identification field, making it no longer available. Use for the purpose of deactivation.

The detailed description is a specific description of a feasible embodiment of the present invention, but this embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or change that does not depart from the technical spirit of the present invention should be included in this case. Patent scope.

The access control machine 200 further includes a card information reading module 201 which reads the identification information column 101 and the card swipe column 102 of the access card 100. The blacklist comparison module 202 compares the identification information column 101 with the card blacklist 203. The bit write-back module 204 writes the number of card swipes into the card swipe count field 102, and the upload module 205 writes the identification information column 101 and the card swipe count field 102. The access control management module 300 further includes a blacklist generation module 301, which generates a card blacklist 203, a database 302 stores the card blacklist 203, and uses the blacklist download module 303 to download the card blacklist 203 to the blacklist comparison module. In group 202, the abnormality detection module 304 compares the identification information column 101 and the card swipe number column 102 of the access card 100.

Please refer to FIG. 2, which is a flow chart of a method for detecting and deactivating an illegal access control card according to the present invention. The steps are as follows: Step S201: When the access control machine senses the access card to swipe the card; Step S202: The access control machine reads the access control card. The information in the identification information column includes the unique serial number of the access control card, the key reading identification information, and the number of card swipes on the card swipe column. First, determine whether the format and content are correct for the access control card; step S203: the access control machine compares the card blacklist If it is an access card that meets the card blacklist, the access control machine writes back the content of the identification information column of the access card to delete the access card; step S204: If it is an access card that does not meet the card blacklist, the access control will be confidential. The key reads the identification information and accumulates the values on the number of times of swiping card, then writes back to the number of times of swiping card of access control card, and opens the door; step S205: the access control device updates the swiping card information, including the swiping time and access control machine number. Passed to the database storage of the access control management module; step S206: the access control management module performs anomaly detection; step S207: read the database with the same identification For each swipe card information, according to the order of the swipe card time, the values of the two swipe card fields are compared, and the values are compared; step S208: if the swipe card card number values are regularly accumulated, it represents a normal access card. The number of times is irregularly accumulated, it is determined that there is an illegal access card; and step S209: a card blacklist is generated and downloaded to the access control machine. When the blacklist card with the identification information column is read and identified by the access control machine next time, the The blacklisted access control will be written back to delete the contents of the card identification field and make it unusable.

The numerical comparison is based on the following logic: d = a (n) -a (n-1); where a (n) represents the value of the next card swipe, a (n-1) represents the value of the previous swipe card, n = 1, 2, 3, 4 ... to the latest one, a (0) is the initial value when the card is issued; when d = constant (> 0), it means that only one card is normally used; and when d = 0 or a negative number, It means that there are multiple cards with the same identification code, which is an illegal access control card.

Among them, the content read by the access control card by the access control machine includes the unique serial number of the card and the identification information read by the key; among them, a certain field in the identification information area read by the key is used as the storage field for the number of card swipes.

To sum up, this case is not only innovative in terms of technical ideas, but also has many of the above-mentioned effects that are not used by traditional methods. It has fully met the requirements of statutory invention patents that are novel and progressive. To approve this invention patent application, to encourage invention, to the utmost convenience.
