Special Issue Information

Dear Colleagues,

Multimedia systems are now widely used in various fields; accordingly, the importance of security and privacy is increasing. It is necessary to develop and apply effective and reliable technologies and methods with which to respond to various threats and attacks that may occur during the creation, transmission, storage, processing, and sharing of multimedia data.

To this end, various efforts are being made to advance technology. We invite researchers working in relevant areas to submit their latest manuscripts which either design new technologies or apply technologies in different multimedia technologies and security areas.

Topics of interest include, but are not limited to, the following:

  • Technologies such as encryption, decryption, authentication, and integrity checking of multimedia data;
  • Technologies such as anonymization, pseudonymization, and de-identification of multimedia data;
  • Technologies such as steganography of multimedia data, digital watermarking and digital rights management;
  • Technologies such as multimedia data breach detection, analysis, and response;
  • Proposals for new models, frameworks and architectures for multimedia data security and privacy;
  • Case studies and applications related to multimedia data security and privacy;
  • Including research related to multimedia.

 Researchers interested in this Special Issue are invited to write and submit a paper.

This paper explores the optimization of quantum circuits for Argon2, a memory-hard function used in password hashing applications. With the rise of quantum computers, the security of classical cryptographic systems is at risk. This paper emphasizes the need to accurately measure the quantum security strength of cryptographic schemes through highly optimized quantum circuits for the target cryptography algorithm. The proposed method focuses on two perspectives: qubit reduction (qubit-optimized quantum circuit) and depth reduction (depth-optimized quantum circuit). The qubit-optimized quantum circuit was designed to find a point where an appropriate inverse is possible and reuses the qubit through the inverse to minimize the number of qubits. The start and end points of the inverse are determined by identifying a point where qubits can be reused with minimal computation. The depth-optimized quantum circuit reduces the depth of the quantum circuit by using the minimum number of qubits necessary without performing an inverse operation. The trade-off between qubit and depth is confirmed by modifying the internal structure of the circuits and the quantum adders. The qubit optimization achieved up to a 12,229 qubit reduction, while the depth optimization resulted in an approximately 196,741 (approximately 69.02%) depth reduction. In conclusion, this research demonstrates the importance of implementing and analyzing quantum circuits from multiple optimization perspectives. The results contribute to the post-quantum strength analysis of Argon2 and provide valuable insights for future research on optimized quantum circuit design, considering the appropriate trade-offs of quantum resources in response to advancements in quantum computing technology.

The outputs of deep hash network (DHN) are binary codes, so DHN has high retrieval efficiency in matching phase and can be used for high-speed palmprint recognition, which is a promising biometric modality. In this paper, the templates and network parameters are both quantized for fast and light-weight palmprint recognition. The parameters of DHN are binarized to compress the network weight and accelerate the speed. To avoid accuracy degradation caused by quantization, mutual information is leveraged to optimize the ambiguity in Hamming space to obtain a tri-valued hash code as a palmprint template. Kleene Logic’s tri-valued Hamming distance measures the dissimilarity between palmprint templates. The ablation experiments are tested on the binarization of the network parameter, and the normalization and trivialization of the deep hash output value. The sufficient experiments conducted on several contact and contactless palmprint datasets confirm the multiple advantages of our method. Full article
