Reconstruction Risk from Vector Representations
向量表示的逆推風險
When an organization converts internal documents to vectors and stores them in a less protected environment, assuming vectors are not themselves sensitive; due to unmitigated control gaps, an attacker obtains the vector data and successfully reconstructs portions of the original content, prompting the organization to recognize that vector storage requires protection equivalent to the source documents, triggering compliance exposure and operational reputational costs.
Framework Mappings
Risk Treatment & Implementation Guidance
Protect vector data with access control and encryption at the classification level of the source documents; Assess embedding-inversion risk, applying perturbation or dimensionality-reduction defenses where needed; Establish in classification policy that derived representations inherit the source's sensitivity level
