  • Patent number: 10887343
    Abstract: Service data is received by a server and from a client computing device, where the service data includes a unique identifier and a variable identifier stored in a local secure storage of the client computing device. The server parses the service data to obtain the unique identifier and the variable identifier as parsed data. The server determines whether the unique identifier and the variable identifier in the parsed data are identical to a unique identifier and a variable identifier associated with the client computing device and recorded by the server as recorded data. If the result of the determination is not identical, the server indicates that the local secure storage of the client computing device is under a copy attack, and performing a predetermined response action. If the result of the determination is identical, the server transmits a new variable identifier to the client computing device.

  • Publication number: 20200130065
    Abstract: A method for producing a water-atomized prealloyed powder with high cold press formability, includes the following steps: (a) preparing a ?400 mesh semi-finished prealloyed powder; (b) controlling the semi-finished prealloyed powder to have a moisture content of 1 wt % to 2 wt % and an oxygen content of 0.6 wt % to 0.8 wt %, and then drying in a vacuum drying oven at 100° C. for 90 minutes to 120 minutes, so that a preliminary bond is produced between powder particles; and (c) reducing, annealing, crushing, and sieving an initially bonded powder particle. The powder is changed from a spheroidal shape to more complex shapes such as “rice ear shape”, “grape shape”, and “satellite powder”, which greatly improves the cold press formability of the prealloyed powder; the method only performs simple surface modification of the powder without changing other properties, and has wide applicability.
