End-to-end encryption (E2EE) poses a challenge for automated detection of harmful media,
such as child sexual abuse material and extremist content. The predominant approach at …

Popular messaging applications now enable end-to-end-encryption (E2EE) by default, and
E2EE data storage is becoming common. These important advances for security and privacy …

Perceptual image hashing methods utilize the visual phenomenon of the images and
produce a fixed-length hash function and this hash value can be utilized for digital signature …

Perceptual image hash is an emerging technology that is closely related to many
applications such as image content authentication, image forging detection, image similarity …

We propose a novel perceptual image hashing based on weighted discrete wavelet
transform (DWT) statistical features. This hashing converts input image into a normalized …

End-to-end encryption (E2EE) prevents online services from accessing user content. This
important security property is also an obstacle for content moderation methods that involve …

Image hashing is an efficient technique of many multimedia systems, such as image
retrieval, image authentication and image copy detection. Classification between robustness …

Data security technology is of great significance for the effective use of high-resolution
remote sensing (HRRS) images in GIS field. Integrity authentication technology is an …

Perceptual image hashing technique uses the appearance of the digital media object as
human eye and generates a fixed size hash value. This hash value works as digital …

Image hashing is an effective technology for extensive image applications, such as retrieval,
