The present invention is directed to a number of improvements in methods for hot-carrier device degradation modeling and extraction. Several improvements are presented for the improvement of building device degradation models, including allowing the user to select a device parameter used to build the device degradation model independent of the device parameter selected. The user can also select the functional relation between stress time and degradation level. To further improve accuracy, multiple acceleration parameters can be used to account for different regions of the degradation process. Analytical functions may be used to represent aged device model parameters, either directly or by fitting measured device parameters versus device age values, allowing devices with different age values to share the same device model. The concept of binning is extended to include device degradation. In addition to a binning based on device width and length, age is added. In an exemplary embodiment, only devices with minimum channel length have degraded models constructed. The present invention also allows the degradation of one device parameter to be determined based on an age value derived from another parameter. In yet another aspect, a degraded device is modeled as a fresh device with a voltage source connected to a terminal.

Provided is a method and device for wear leveling of a non-volatile data storage device, thereby storing an aging value indicating a write time in each data unit of the non-volatile data storage device, and based on the aging value Detect static data areas to maximize wear leveling. The method includes: storing an aging value indicating a write time in each cell allocated to write data therein; reading the aging value stored in the cell; and determining a static data area based on the read aging value. Therefore, the static data area can be correctly detected without increasing computational overhead, and the wear leveling effect of the entire storage device can be increased by moving data to and from the static data area, thereby prolonging the lifetime of the storage device.

The invention provides an age recognition method based on facial features. The age recognition method based on facial features comprises the following steps: obtaining a face image and capturing the face area; setting feature points on the captured face area image; confirming an age feature area on the face area according to the coordinates of feature points; extracting the age features on the face area image and obtaining the corresponding age value; and judging the age by comparing the age value with the preset threshold.

An immunization method for user behavior detection in the electronic transaction process comprises a data preprocessing step in which the operation process of a user is processed into a sequence format and related repeated data is cleaned, a training step in which the age value of each sequence is calculated in chronological order and according to the age evolution process, aged logs are deleted according to the age values, and a normal sequence library (namely, antibody) is extracted, a detection step in which whether a newly generated transaction sequence is mutated is detected, and an updating step in which the autologous and allogeneic age values are updated in a timely manner and a related library set is updated. The immunization method is designed for abnormal situations in the electronic transaction process, which may be misoperation by users, illegal operation caused by false account use, or other situations not in accordance with behavior habits of users. The immunization method for user behavior detection in the electronic transaction process is provided for e-commerce and third-party payment platforms, and has the characteristics of being controllable and preventable, adaptive, self-learning, and the like.
