In this paper, we introduce two new image-sharing types to extend the applicability of sharing. Type 1 is our so-called forbidden type. In its sharing system, any t of the n shares can recover the secret image, unless the t shares form a forbidden gr

This study presents an authentication method with self-recovery ability. The hidden watermark in the proposed method not only detects and locates the tampered portion of an image, but also self-recovers the tampered portion. To increase the ability t

The conventional encryption techniques of visual cryptography are extended to web page. The key point is that Cascading Style Sheet blend modes can simulate stacking operators. The multiply blend mode can be regarded as Boolean OR operator, and the d

This paper proposes a cross recovery scheme to protect a group of 3D models. The lost or damaged models can be reconstructed using the mutual support of the survived authenticated models. In the encoding phase, we convert a group of n given models (c

Portable Document Format (PDF) is a popular file format to store documents. Protection of PDF files is thus important. In this paper, we present a (t, n) PDF-sharing scheme which shares the given secret PDF file F among n stego-PDF files. Each stego-

K-means clustering method has been widely used in many areas. However, it is time-consuming when data are in high dimensional space, or when there are many clusters. We try to accelerate its speed by combing our previous work with the simplest versio

Synchronizing Two Frequently-Cited High-Capacity Image Hiding Methods (Modulus-Based Vs. LSB-Based) This study briefly reviews and then connects a Modulus-based image hiding method published in 2003 and an LSB-based (Least- Significant-Bits) image hi

The K-means method is a well-known clustering algorithm with an extensive range of applications, such as biological classification, disease analysis, data mining, and image compression. However, the plain K-means method is not fast when the number of

This paper proposes a flip visual cryptography (FVC) scheme with perfect security, conditionally optimal contrast, and no expansion of size. The proposed FVC scheme encodes two secret images into two dual-purpose transparencies. Stacking the two tran
