The legislature passed on first reading Thursday a proposed law that would keep secret personal data. This includes telephone numbers, photographs and home addresses.
Casa Presidencial praised the measure as a boost for foreign investment because business people can keep their information secure.
The proposed law targets credit reporting agencies and sales people who would use information to contact potential customers.
In effect, the proposed law would create new rights for individuals, but it would not affect the ability of the government to use its own data bases for investigative reasons.
To become law, the measure would have to be passed a second time and signed by President Laura Chinchilla. who supports the measure. The second approval is likely next week.
