The present invention is adapted for recognition technology improvement, which provides a memory identification and recovery method based on recognition, including: S1. collecting the data information from the scene of activity through a recognition device; S2. conducting salient feature extraction to the data information collected from the scene and generating feature marks; S3. building mapping relations between the generated feature marks and the extracted data information, automatically generating memory information in the database, and storing the information in the database; S4. inputting related data information for searching; S5. selecting a corresponding method to search the generated memory information in the database based on the input data information; S6. determining if there is related data information in the memory data. The method can helps to enhance memory of the user, recover memory after forget it, recover effectively through recognition technology, improve memory, and retrieve memory quickly after memory loss, which is convenient and efficient.
