A novel data protection technique aims to neutralize the impact of complete personal data breaches by embedding real records inside an enormous set of plausible alternatives.
The proposed method addresses a worst-case scenario in which an attacker obtains a file containing fully dissolved personal information, including telephone numbers, email addresses, passport details, residential addresses, INN, and SNILS. In the demonstration, the message provides almost everything an attacker would need: 361 characters total, 317 characters without spaces, 45 words, the PIN code, and the original word order.
What remains hidden is the secret vector space and the assembly algorithm. According to the author, this absence renders all other data useless because exhaustive search becomes astronomically infeasible. Any attempt at reconstruction yields millions of semantically valid variants, yet the attacker has no way to determine which variant corresponds to the original record.
The technique is positioned as a practical defense for situations where traditional encryption is impractical or when data must stay usable by legitimate systems while remaining resistant to extraction. Interested parties can experiment with the approach through a dedicated sandbox environment.
