<p>Provided are an information security processing method and device. The method includes: storing the device feature code or the variation code thereof in the one-time write-in region of the chip of a device so as to establish a locking relationship between the device and the device feature code; and checking the locking relationship between the device and the device feature code, wherein when it is found that the device feature code or the variation code thereof does not accord with the device, the device cannot work normally, or when it is found that the device feature code or the variation code thereof accords with the device, the device works normally. By way of the solution mentioned above, the device feature code or the variation code thereof can be stored in the one-time write-in region of the chip of the device, thus realizing an information security processing function with a high security level, effectively preventing illegal users from copying or stealing numbers and protecting the interests of manufacturers, operators and users.</p> |
