Latest Patents

Yufei Hu holds 1 patent for a "Backdoor attack method and system for classification task in code model." This patent discloses a method that includes several steps: first, collecting and preprocessing clean samples to obtain important variable names. Next, the variable names of the clean samples are classified according to label categories to obtain multiple trigger sets, while selecting target labels from the clean samples. The method then involves performing score calculations on the variable names in the trigger sets corresponding to the target labels. One important variable name is replaced with the variable name having the maximum C score in the clean samples to create poisoned samples. This process is repeated until the labels are changed into the target labels. Finally, triggers are randomly inserted into the poisoned samples to form negative samples, which are then used to perform an attack using an attack model based on the negative, poisoned, and clean samples.
