Cipher disk

Abstract: The invention discloses a method and a system for realizing CAPTCHA verification using a cipher disk, and relates to the technical field of CAPTCHA processing. The method comprises the following steps: a user side sends a CAPTCHA information request to a server side; after receiving the request, the server side randomly selects a real CAPTCHA and generates corresponding CAPTCHA information; the server side obtains prompt information through a randomly selected elementary arithmetic according to the real CAPTCHA, and sends the CAPTCHA information and the prompt information to the user side; after receiving the information, the user side draws a circular cipher disk containing the real CAPTCHA, and shows the prompt information; a user inputs data by rotating the cipher disk according to the prompt information; the user side records the data and uploads the data to the server side; the server side verifies the data and returns a verification result; and the user side carries out corresponding processing according to the verification result returned by the server side, and gives a feedback to the user. According to the invention, CAPTCHA can be effectively prevented from being cracked maliciously, the verification effect of CAPTCHA can be enhanced, and high security is achieved.

Abstract: The utility model relates to an inserting cipher lock core and a special key which resolve the problem that present cipher lock is easy to unlock. The inserting cipher lock core of the utility model comprises a casing with a graduated circle, and a lock shaft is provided in the casing. The utility model is characterized in that the lock shaft is provided with a rotary lock disk, a plurality of cipher disks and a end-face cipher disk which are provided with a plurality of mutually corresponding keyholes and mutually pushing block piles on their disks, a plurality of pin tumbler holes corresponding to the keyholes of the cipher disks are provided in the casing, the pin tumbler hole is equipped with a spring and a pin tumbler in it, a special key matching the cipher lock core has a cylindrical key body in which a plurality of inserted bars corresponding to the keyholes of the rotary lock disk, the cipher disks and the end-face cipher disk are provided, the inserted cars are used to make the keyholes mutually corresponding, in order to push the pin tumbler to the open position, then the lock is opened through turning the lock shaft.

Abstract: The utility model relates to a self-regulating puzzle lock, which solves an abuse caused by lock changing or key duplicating after a key is lost The utility model comprises a lock head, the key and a cipher regulation rod which are correspondingly divided into over two sections, wherein, every two sections of a rotating lock core wheel in the lock head are connected by a lock core insertion rod to form one body, and each section of the lock core wheel is provided with a marble hole and marbles; every two section of a rotating key wheel in the key are connected by a key core rod into one body, teeth of the periphery of the rotating key wheel are corresponding to the marbles, and cipher numbers are marked on the teeth; the cipher regulation rod is provided with depth marks, regulation teeth and a cipher disk The utility model has the advantage of randomly regulable ciphers, so the utility model has higher security

Abstract: The utility model relates to a mechanical cipher lock core, comprising a rotary lock and a cipher lock body. The utility model is characterized in that the inner part of the cipher lock is provided with a numerical cipher disk which is composed of a plurality of cipher plates and a plurality of reset plates, and is also provided with a plurality of shifting hooks which are corresponding to the numerical cipher disk. Because the shifting hooks are mutually matched with the cipher plates and the reset plates, the numerical cipher disk can be moved towards the unlocking direction and the lock can be opened when the numerical code disk is operated according to the order of the cipher. The numerical cipher disk can be reset and the lock can be closed when the numerical cipher disk is operated without according to the order of the cipher. The purpose that the lock is opened by the cipher can be attained. The utility model has the advantages of good secret performance and difficult decipher, can be operated without leaking the cipher in the public situation, and can also be matched with the lock-tongue portion of the new and the old spring locks and is an ideal mechanical cipher lock core.
