摘要：Many basic tasks in computational biology involveoperations on individual DNA and genomic sequences. These sequences, even when anonymized, are vulnerable to re-identification attacks and may reveal highly sensitive information about individuals. To support large-scale biomedical research projects, organizations need to share person-specific genomic sequences without violating the privacy of their data subjects. We present a relatively efficient, privacy-preserving implementation of fundamental genomic computation without disclosing the raw genomic sequences. Organizations contribute encrypted genomic sequence records into a centralized repository, where the administrator can perform queries, without decrypting the data.
