A Secure Image Authentication Scheme with Tamper Localization and Recovery [PDF]
, 2021 This paper proposes a secure image authentication scheme that can locate the tampered regions, recover the lost contents and hide application-specific sensitive data. In this scheme, an encrypted watermark that comprises tamper localization, recovery and application-specific information is placed in the selected pixels, which is extracted and decrypted

Retention of data in heat-damaged SIM cards and potential recovery methods
, 2007 Examination of various SIM cards and smart card devices indicates that data may be retained in SIM card memory structures even after heating to temperatures up to 450oC, which the National Institute of Standards and Technology (NIST) has determined to be
