Distortion-Free Secret Image Sharing Mechanism Using Modulus Operator [PDF]
, 2009 [[abstract]]The (t, n)-threshold has been extended to secret image sharing due to its practicability. In this article, we provide a novel version that employs the modulus operator to embed the secret share into a host image.

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network
Laser &Photonics Reviews, EarlyView.This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Mobilizing Presence across Borders: Devotion to Papua New Guinea's Blessed Peter To Rot in Australia
Oceania, EarlyView.ABSTRACT This article engages with the conjunctures between migration and religion by focusing on the celebration of Papua New Guinea's ‘National Patron Saint’, the Blessed Peter To Rot, in the Australian diaspora. Both in Sydney and Brisbane, Catholic Papua New Guinea (PNG) migrants have been ‘relocating’ PNG shrines, regalia, relics and ritual ...

A self-authentication mechanism for a (3,3)-threshold secret sharing scheme [PDF]
, 2012 [[abstract]]Secret sharing is widely used in secret image protection since 1979. Image secret sharing schemes are used to encrypt the secret image into several meaningless share images. Later on, the secret image can be reconstructed while collecting the

Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

A study of optimally essential secret image sharing scheme [PDF]
, 2017 碩士本論文提出一個兩層式結構的(t, s, k, n)關鍵秘密影像分享門檻技術，當中有s個關鍵分享影像和n-s個非關鍵分享影像，且還原回秘密影像時，需收集t個關鍵分享影像和k個分享影像，其中分享影像包括關鍵分享影像和非關鍵分享影像。在此技術中定義一個參數m，m=1時，將獲得最小的總分享影像的影像大小及關鍵分享影像的影像大小接近於非關鍵分享影像的影像大小；m=t時，將獲得關鍵分享影像的影像大小和非關鍵分享影像的影像大小為2倍關係，並且能凸顯關鍵分享影像的重要性，此外，本論文克服前人Chen的方法[3 ...

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Lossless and Unlimited Multi-image Sharing Based on Chinese Remainder Theorem and Lagrange Interpolation [PDF]
, 2014 [[abstract]]This study proposes a novel multi-image threshold sharing scheme based on Chinese remainder theorem and Lagrange interpolation. The exceptional property of the scheme is its ability to retrieve any secret image without recovering all the ...
