The embodiment of the invention provides a signature unlocking method, an intelligent interaction tablet and a storage medium, and belongs to the technical field of intelligent equipment unlocking. The method comprises the following steps: receiving a signature code input by a user and a first handwritten signature of the user on a touch interface; the signature code is a number with a preset length; sending the signature code to a server, so that the server searches a target account corresponding to the signature code; a mapping relationship between the account and the signature code is stored in the server; and receiving preset verification data of the target account fed back by the server, and performing signature verification on the first handwritten signature of the user based on the preset verification data so as to unlock the target account when the first handwritten signature of the user passes the signature verification. According to the method, the user can quickly and safely unlock the personal account on different devices without setting verification data on the different devices in advance, and correspondingly, different users can quickly and safely unlock the personal account on a public device without setting verification data on the public device in advance.

The invention relates to the field of infrared touch screen control, in particular to a control method and system of an infrared touch screen. The method comprises the following steps: acquiring a transmitting unit set, a receiving unit set and a forbidden list, performing topology registration and signature codebook library assembly processing, and generating a scanning configuration packet; on the basis of the scanning configuration packet, executing transmission lightening time slot sequence generation, receiving time slot sampling and dark time slot baseline deduction matching decoding processing, and generating a decoding evidence packet; based on the decoding evidence packet, baseline offset calculation is carried out, spatial form evidence and time consistency evidence generation processing is carried out, a gating evidence packet is constructed, evidence gating and anomaly classification processing is carried out, and a control output packet is generated; and extracting a verification rescanning strategy parameter from the control output packet, executing verification rescanning and passing mark generation processing, generating a rescanning result packet, and constructing a write-back update packet. According to the invention, through an evidence link and a re-scanning write-back closed loop organization, the caliber consistency and traceability of control output are improved.

The embodiment of the invention provides a code generation method, computing equipment and a storage medium. The method comprises the following steps of: identifying function information respectively corresponding to a plurality of original expansion functions for chained calling from a to-be-processed packet which is generated by compiling a source file based on a Kotlin language; the function information comprises function signature information; for each original extension function, converting the parameter type of each parameter in the function signature information from a non-null type to a null type to generate converted function signature information; on the basis of the converted function signature information, a function signature code and a function body code are generated, and the function body code is configured to call the original spread function under the condition that the parameter value is judged not to be empty, and return to the current object under the condition that the parameter value of any parameter is empty; and writing the function signature code and the function body code into a source code file of the target extension function and storing. According to the technical scheme provided by the embodiment of the invention, the chained calling of the target extension function can be realized without interruption.

This invention discloses a method, device, equipment, and storage medium for security monitoring of power mobile terminals. The method includes: acquiring Java layer behavioral signature codes, Native layer behavioral signature codes, and Kernel layer behavioral signature codes; analyzing and comparing the Java layer behavioral signature codes, Native layer behavioral signature codes, and Kernel layer behavioral signature codes to obtain Java layer hidden behavioral signature codes and Native layer hidden behavioral signature codes; using a preset business security threat policy library as a reference standard, calculating the similarity between the application's Java layer behavioral signature codes, Native layer behavioral signature codes, Kernel layer behavioral signature codes, Java layer hidden behavioral signature codes, and Native layer hidden behavioral signature codes and the reference standard to determine the application's category; and by analyzing the malicious behavior audit of the power mobile terminal and the applications running on it, combined with the terminal business security threat policy library, rapid identification and interception of malicious behavior can be achieved.

The invention discloses a card number traceability anti-counterfeiting generation method and system for an exchange card. The method comprises the following steps: generating 16-bit plaintext data; wherein the 16-bit plaintext data comprises three plaintext sub-parts; performing encryption hash processing and byte interception processing on the 16-bit plaintext data to obtain a 7-bit decimal short code; accessing the 7-bit decimal short code into 16-bit plaintext data to obtain 23-bit data; generating a 1-bit check code according to the 23-bit data; accessing the 1-bit check code into 23-bit data to obtain a 24-bit card number; and offline verification is carried out on the 24-bit card number, so that whether the 24-bit card number is qualified or not is judged. In a 24-bit pure digital space, a 16-bit plaintext + 7-bit ECDSA signature + 1-bit Luhn verification code is used for forming a signature code capable of being verified offline, a signature value is taken from a cryptographic random number of a standard elliptic curve private key, a Merkle tree is constructed at a time, root hash is written into a non-tampering medium, logistics, sales, exchange and other events are added step by step to form a chained log, and the chained log can be verified offline. And double anchoring of closed batches and additional events is realized.
