Cryptanalysis of secret sharing schemes based on spherical spaces

In this article the analysis of secret sharing scheme developed by Tan, Yang, Cheng and Wang, in which taken as the basis for personalized spherical spaces. This method is a threshold secret sharing scheme in which secret itself is represented as a center of the sphere, and its shadows as points on the surface of the sphere. But in this article proposed a method of unleash the secret in a fairly short time.
