  • Patent number: 9014372
    Abstract: This discloses a video file encryption and decryption method, device, and mobile terminal. The encryption method can include: obtaining a to-be-encrypted video file and an encryption key, encrypting the video file using the encryption key to obtain an encrypted video file, obtaining scanned non-hidden partitions of a mobile terminal and an extended memory of the mobile terminal for storing user data, determining a partition storing the to-be-encrypted video file among the non-hidden partitions, and moving the encrypted video file to a folder in the partition storing the to-be-encrypted video file. The decryption method can include: obtaining a to-be-decrypted video file and a decryption key, decrypting the to-be-decrypted video file using the decryption key to obtain a decrypted video file, and determining a pre-encryption storage location of the to-be-decrypted video file and moving the decrypted video file to the pre-encryption storage location of the to-be-decrypted video file.

  • Patent number: 6844208
    Abstract: A method for monitoring a dose of a silicon bearing implant is described. The method includes introducing a first implant species through a surface of a semiconductor substrate at a first does of energy level and introducing a silicon bearing species through the surface of the semiconductor substrate at a second dose and a second energy level. The method anneals the semiconductor substrate and measures a sheet resistance value of the surface of the semiconductor substrate. The method also determines the second dose value based upon the surface resistance value.
