News
May 2024: We propose a new computionally hard problem called Learning With Quantizaion (LWQ). Quantization means dropping a few bits, which induces errors. https://eprint.iacr.org/2024/714
April 2024: We prove that the optimal quantizer can be designed by polar lattices. https://arxiv.org/abs/2405.04051
April 2024: A few papers on using lattice algorithms and structures for data hiding have been published: i) reversible data hiding by difference contraction: https://ieeexplore.ieee.org/document/10247563. ii) attacking spread spectrum data hiding by lattice algorithms: https://ieeexplore.ieee.org/document/10534263. iii) robust quantization index modulation: https://ieeexplore.ieee.org/document/10356112.
