Terasing

Terasing is a term used to describe the deliberate removal, obliteration, or concealment of information, traces, or records, especially within digital systems. The concept encompasses formal deletion, redaction, data minimization, and, in some discussions, erasure that leaves only partial or obscured traces. The word is a neologism formed from erase with the -ing suffix and is encountered primarily in information governance, memory studies, and critical technocultural theory rather than in standard technical glossaries. Its usage signals attention to how memory and records are shaped by decisions about what to keep and what to remove.

Contexts and methods: In IT and data governance, terasing may involve secure deletion, cryptographic erasure (destroying keys so data cannot be read), and hardware sanitization. In archiving and history, terasing raises questions about fidelity, provenance, and the completeness of the record when portions are removed or redacted. In political or media contexts, terasing is discussed as a tool of censorship or as a means of influencing public memory by controlled retention of information.

Ethics and governance: Terasing intersects with privacy, accountability, and the public interest in accessible information. Legal regimes governing data protection, freedom of information, and archival mandates influence when and how terasing is permissible. Critics warn that pervasive terasing can undermine transparency and historical accountability, especially when governance processes lack verifiable documentation.
