7results about How to "Avoid identification" patented technology

This invention relates to an active learning-based data-free black-box attack method and system based on multidimensional value assessment, belonging to the field of artificial intelligence security technology. This method constructs a pre-emptive "sample screening funnel," utilizing a local substitution model to perform multidimensional assessments of sample boundary approximation, information uncertainty, and geometric diversity before sending images to a commercial cloud API. Only high-value samples are selected for querying, thereby achieving low-cost, high-efficiency model theft and adversarial attacks. This invention ensures the diversity and training stability of data-free generated samples, significantly improves the transfer success rate of adversarial examples, and achieves "low-cost, low-risk" economical attacks. It has strong versatility and can be seamlessly integrated into various existing data-free attack frameworks, facilitating deployment and implementation in practical security assessment systems.

The calculation module and the image recognition module are both connected with the controller, the controller controls the ticket checking gate to be opened or closed for ticket checking according to the weight collected by the mass sensor and the number of people recognized by the image recognition module, the number of people entering the elevator and the weight of people entering the elevator are accurately controlled, and overload of the elevator is effectively prevented.

A user equipment (“UE”) in a wireless communication network can generate a padded identifier by inserting a string of padding bits in a field of an identifier associated with the UE. The UE can further encrypt the padded identifier to generate a hidden padded identifier. The UE can further transmit the hidden padded identifier to a network node operating in the wireless communication network.

This invention relates to a method for multi-factor authentication passwords. It automatically generates corresponding matching features by continuously recording the relatively fixed characteristics of a user's password input habits, and automatically invokes these matching features for verification in case of verification anomalies. Because these matching features possess strong personal characteristics and long-term stability, they significantly improve security against technical decryption, brute-force attacks, and credential stuffing attacks. Furthermore, these matching features do not require separate configuration, achieving the technical effect of improving password verification security and reliability without increasing the user's learning cost or verification methods.

The present application relates to the technical field of unmanned aerial vehicle signal identification, and discloses an unmanned aerial vehicle signal identification method, an electronic device and a computer readable storage medium, the method comprising: obtaining a target signal image obtained by detecting a target unmanned aerial vehicle, the target signal image comprising frequency distribution information of a target signal; the duty ratio of the target signal is greater than a preset duty ratio threshold; amplifying the resolution of the target signal image according to a preset amplification factor to obtain an amplified signal image; identifying a plurality of edge contours of a target signal in the amplified signal image to obtain a plurality of first target areas on the amplified signal image; and reducing the resolutions of the plurality of first target areas according to a preset magnification factor to obtain a plurality of second target areas so as to identify target information of the target unmanned aerial vehicle according to the plurality of second target areas. In this way, the accuracy of unmanned aerial vehicle signal identification is improved.

This invention relates to the field of smoke sensors and discloses a mine smoke sensor that is easy to maintain. The smoke sensor includes a fixed base on its top, a resistance structure surrounding its side, and a cleaning structure surrounding the side of the resistance structure. The cleaning structure includes an air pressure tube, a piston slidingly mounted inside the air pressure tube, and a movable rod on one side of the piston. The cleaning structure provided by this invention is linked to the battery compartment. When the operator opens the battery compartment for battery replacement or equipment maintenance, pulling the external pull ring synchronously moves the movable rod and piston outward, filling the air pressure tube with air. During battery replacement and when the battery compartment is closed, the piston pushes inward, evenly discharging the stored air through multiple cleaning tubes, effectively blowing away dust accumulated on the sensor surface. This is especially beneficial if the sensor surface has firmly adhered dust.

The invention discloses a trabectedin-loaded nano-micelle and oxaliplatin-loaded drug combination composition and application, and relates to the technical field of delivery and drug combination, and the trabectedin-loaded nano-micelle and oxaliplatin-loaded drug combination composition comprises trabectedin-loaded nano-micelle and oxaliplatin. The invention also discloses an application of the combined pharmaceutical composition in preparation of antitumor drugs. According to the invention, a pH-sensitive amphiphilic biodegradable material (such as PCL-PEOz) and a chemical drug are self-assembled to form stable micelles, so that the bioavailability of the drug is improved, the critical concentration of the micelles is reduced, and long-acting circulation in vivo is realized; the system can be combined with oxaliplatin for use, so that the sensitivity of tumor cells to oxaliplatin is promoted, the synergistic effect of chemotherapy and immunotherapy is exerted, the treatment effect of malignant tumors is improved, and the tumor microenvironment is improved.
