排他性攻击下的长期数据共享

Long-term Data Sharing under Exclusivity Attacks

Technion - Israel Institute of Technology(以色列理工学院)

Yotam Gafni, Moshe Tennenholtz

摘要:

学习的质量通常随着数据的规模和多样性而提高。因此,公司和机构可以从建立基于共享数据的模型中受益。许多云和区块链平台以及政府计划都有兴趣提供这种服务。这些合作努力面临一个挑战,我们称之为“排他性攻击”。一家公司可以分享扭曲的数据,这样它就可以学习最佳的模型拟合,但也可以误导他人。我们研究协议的长期互动和他们的脆弱性,这些攻击,特别是回归和聚类任务。我们的结论是,协议的选择,以及攻击者可以控制的Sybil身份的数量,是材料的脆弱性。

英文摘要:

The quality of learning generally improves with the scale and diversity of data. Companies and institutions can therefore benefit from building models over shared data. Many cloud and blockchain platforms, as well as government initiatives, are interested in providing this type of service. These cooperative efforts face a challenge, which we call ``exclusivity attacks''. A firm can share distorted data, so that it learns the best model fit, but is also able to mislead others. We study protocols for long-term interactions and their vulnerability to these attacks, in particular for regression and clustering tasks. We conclude that the choice of protocol, as well as the number of Sybil identities an attacker may control, is material to vulnerability.
