Expired Passwords: The Obsolescence of Biometric Security Systems
The project analyzes the residual persistence of physical access systems within an ecosystem dominated by biometric protocols, automated authentication, and algorithmic identity management. The mechanical key is treated as a terminal device: a material fragment that has survived operational infrastructures that have now migrated toward invisible computational environments.
The investigation employs a rigorous serial cataloging to transform each object into an isolated taxonomic unit. Its original function is suspended through its extraction from the operational context and the absolute standardization of its representation. The image no longer documents the object's use, but rather its state of systemic obsolescence.
The grid acts as a coercive archival structure. Each morphological variation is reduced to a minimal difference within a closed dataset, simulating the behavior of contemporary automated recognition systems and biometric databases.
Deactivation of Function
The photographed keys maintain no active relationship with the spaces they once protected. Doors, buildings, and infrastructures are absent from the image. The system deliberately eliminates every narrative or environmental element to prevent any nostalgic or documentary reading.
The object survives exclusively as an administrative trace. Photography therefore operates as an inventory procedure: a flat, repetitive, and standardized recording of devices stripped of their operational efficacy.
Seriality nullifies the singularity of the object. Even the differences between industrial models, surface wear, or identifying engravings are absorbed within the regular structure of the grid. The image constructs no visual hierarchies; each element occupies the same logical space and performs the same archival function.
From the Mechanical Profile to Biometric Data
The project establishes a structural continuity between the physical key and contemporary biometric technologies. Both systems operate through the extraction of identifying patterns and the automated verification of access. The material medium changes, but the logic of control remains.
The mechanical key contains a notched profile readable by a physical system. Contemporary biometric systems replace that profile with facial data, fingerprints, eye scans, or behavioral statistical models. In both cases, identity is reduced to a verifiable sequence.
However, the obsolescence of the mechanical object introduces a critical vulnerability: when the operating system is decommissioned, the material code immediately loses its validity. The key remains as a residual body incapable of producing access.
This condition is used as a model to analyze the fragility of contemporary biometric infrastructures. If identity is treated exclusively as machine-readable data, the synthetic simulation of identity itself becomes a structural problem of the system.
Corruption of the Dataset
Photographic isolation progressively transforms the keys into elements comparable to corrupted strings of code. Systematic repetition produces a visual compression effect: the object ceases to be interpreted as a tool and is perceived as a numerical variant within a matrix.
Photography here operates according to a logic close to operational images. It is not constructed for aesthetic contemplation or individual expressiveness, but for classification, comparison, and indexing.
Furthermore, the high uniformity of the sequence produces a controlled loss of contextual information. The object remains legible in its physical structure, but is progressively separated from the function that guaranteed its operational meaning.
The grid thus simulates an archive of failed authentications: a set of residual credentials incapable of interacting with the infrastructure for which they were generated.
