Abstract: A firmware updating system and method are provided. The firmware updating method includes configuring a host to digitally sign a firmware to be updated, and configuring an electronic device to perform an authorization verification on an update tool, and only the update tool that passes the verification has an update permission. The update tool uses an encryption algorithm to encrypt the firmware to be updated that includes a digital signature. After the encryption is completed, the host sends the update tool to the electronic device through the update tool. The electronic device then uses a decryption algorithm to decrypt the received firmware to obtain the firmware to be updated including the digital signature, and write the firmware to be updated into a firmware storage area to be updated. The electronic device then verifies the digital signature in the firmware to be updated.

Abstract: A self-learning, self-healing database-management system determines that erroneous input, such as an improper SQL query, has caused a critical database condition. The system parses each input statement into a set of tokens, and then translates each set into lines of a failure script. The script is consolidated by cross-referencing each line to infer relationships between input statements. The system then searches historical database logs for previously entered, error-free input similar to the erroneous input. A degree of similarity between the erroneous input and each previously entered input is determined by a computational method that quantifies similarities between the failure script and each script generated from a previously entered input. The system revises the erroneous input to more closely match the most-similar previously entered input and resubmits the corrected input. The results of the resubmission are used to train the system to more accurately correct future input errors.
