, 2010 碩士資訊隱藏技術是一種新發展的秘密通訊技術，近年來許多學者陸續提出各式各樣關於影像隱藏的系統，我們發現大多數的資訊隱藏系統利用單張影像來隱藏機密訊息，也許我們可以將這些技術利用在影片之上，為了達成需求，我們提出一個新的資訊隱藏系統，此系統以LSB資訊隱藏技術為基礎，另外利用三维陣列的概念來輔助我們所提出的系統，由實驗結果證明，本系統可以達成我們的需求，在影片上實現資訊隱藏且不容易被察覺。Data hiding technique is a new kind of secret communication

Advanced Materials, EarlyView.Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

Dual‐State Programmable Oxide Transistor for Time‐Based Cryptography
Advanced Materials, EarlyView.A DUPOT enables independently tunable Vth and Isat depending on gate bias polarity, producing three‐dimensional dynamical behavior within a transfer characteristic. This behavior originates from charge trapping and oxygen‐ion migration in the HfO2 layer.

A Magic Cube Based Information Hiding Scheme of Large Payload
, 2016 [[abstract]]Hiding information on grayscale images has been drawing much attention in recent years. In pervious techniques, many schemes like Zhang and Wang's method or Sudoku method use magic matrix as a plane reference to modify the LSBs of cover ...

Inverse Design of Nanoparticulate Materials
Advanced Materials, EarlyView.Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Reversible Steganography for VQ Indices Using the Modified State Codebook
, 2010 [[abstract]]In this paper, we propose an information hiding scheme to embed secret information into the compression code of an index table. First, the codewords neighboring the current processed index along with their closest codewords form a state ...

Advanced Materials, EarlyView.Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Advanced Materials Interfaces, EarlyView.By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...
