Eticas OASI — a Civil-Society Register of Harmful Algorithms, 149–152 Systems Logged With Audit Status

The Observatory of Algorithms with Social Impact (OASI) is run by the Eticas Foundation, a Barcelona-based non-profit. It is a public, searchable register of algorithms used by governments and companies on citizens. Each entry records who developed and who uses the system, its scope and objectives, social impact and threats, the sources consulted, and whether it has been audited.
OASI launched in 2021 with 57 algorithms. A Catalan government ICT-network article (February 2023) cites 149 algorithms, 24 of them applied in the US by government and large tech companies, and a Dutch trade publication (December 2023) reports 152 descriptions. Entries span public systems such as the Rotterdam fraud model and SyRI, and private ones such as TikTok, Google Search and Deliveroo, and are not limited to Spain.
Eticas states that it aims to register algorithms shown to have some negative social impact, drawing on press reports, academic work and direct outreach. The register is therefore selective rather than exhaustive, and audit status is recorded only where known. Eticas has three employees according to the Dutch report, so continuity depends on a very small organisation.
Caveat: no source reviewed documents a regulatory or policy change attributable to OASI. Its value is as an independent, cross-border complement to official algorithm registers, which tend to list only what governments choose to disclose.
