Brazil: Bill amending Law No. 15.211 to establish technical standards for detecting child sexual abuse material and improving transparency mechanisms (Bill No. 4880/2025) was introduced in Chamber of Deputies

On 1 October 2025, the Bill No. 4880/2025 was introduced in the Chamber of Deputies to amend Law No. 15.211 of 17 September 2025, known as the Digital Statute of the Child and Adolescent, to establish specific technical standards for the detection of child sexual abuse material and to enhance transparency mechanisms. The Bill requires providers of information technology products and services with upload, sharing or audiovisual transmission functionalities to implement automated detection systems, including cryptographic hash comparison with recognised databases, nudity detection algorithms with age estimation based on anthropometric criteria, contextual automated analysis to identify sexual exploitation situations, and machine learning systems for emerging patterns of child sexual abuse material. These systems must be auditable by accredited third parties, with implementation deadlines of 90 days for providers with more than 10 million users, 180 days for those with more than 1 million users, and 360 days for all other providers. In addition, the Bill mandates detailed transparency reports covering detection results, average removal times, reports to authorities, algorithm precision rates, and investments in protective technologies, to be consolidated and published in an online panel managed by the autonomous administrative authority for the protection of children’s rights in the digital environment.
