Dataprev - social security as a computing problem
Formed from the merged data centres of the social security institutes, and still holding the record of who is owed what.
Dataprev was created in 1974 from the merger of the data processing centres of Brazil's social security institutes, and it runs the systems that decide whether a pension is paid. Its records are the national employment and contribution history, which makes it one of the few systems whose correctness is directly a person's income.
The scale is easy to state and hard to appreciate: a benefit calculation depends on a contribution history that may span fifty years, recorded by institutions that no longer exist, on formats that changed repeatedly. Every migration in that estate carries the risk of losing somebody's working life.
It belongs on this timeline beside Serpro because the two together are what Brazilian state computing actually is - not a policy, but two organisations holding records that predate most of the technology used to hold them.
