This study explores three-dimensional multi-channel quantum image representation model (3D-QRMW) which can be used in many fields such as three-dimensional medical imaging, atomic imaging, and infrared images. Quantum images are transmited between participants by Quantum Fourier Transform (QFT) in which output qubits are reordered by blind Cloud with permutation. Also key with length K=16N is applied to share signature for recipients. This allows all members to know only their signature information. Security analyzes show that quantum images in the model of 3D-QRMW are transmitted safely. Keywords : 3D quantum image, Security of 3D quantum image, Blind Cloud, Quantum Fourier.

Quantum secret sharing (QSS) is an important branch of secure multiparty quantum computation. Several schemes for
(n,n) threshold QSS based on quantum Fourier transformation (QFT) have been proposed. Inspired by the flexibility of
(t,n) threshold schemes, Song {\it et al.} (Scientific Reports, 2017) have proposed a
(t,n) threshold QSS utilizing
QFT. Later, Kao and Hwang (arXiv:1803.00216) have identified a loophole in the scheme but have not suggested any remedy. In this present study, we have proposed a
(t,n) threshold QSS scheme to share a
d dimensional classical secret. This scheme can be implemented using local operations (such as
QFT, generalized Pauli operators and local measurement) and classical communication. Security of the proposed scheme is described against outsider and participants' eavesdropping.
