Infographic titled “Data access policy proposals and their impact on the open, globally connected, trustworthy, and secure Internet.” The graphic is divided into two sections. The upper green section, marked with a thumbs-up icon, is labeled “Does not interfere with the technical foundations of the Internet” and states that these approaches enable effective investigations without weakening encryption. It lists five recommended investigative methods: (1) User reporting, (2) Undercover investigation techniques, (3) Voluntary cooperation, (4) Analysis of metadata, and (5) Forensics on seized devices. Each item includes a brief description and a thumbs-up symbol. An upward arrow on the left indicates stronger protection of the Internet’s technical foundations. The lower red section, marked with a thumbs-down icon, is labeled “Interferes with the technical foundations of the Internet” and states that these approaches create systemic risks that can be exploited. It lists three measures: (6) Remote forensic software, (7) Client-side scanning, and (8) Mandated backdoors. Each item includes a brief description and a thumbs-down symbol. A downward red arrow on the left indicates increasing harm to the Internet’s technical foundations. The overall message is that some investigative techniques can support law enforcement while preserving encryption and Internet security, whereas others weaken encryption or create systemic vulnerabilities that undermine the Internet’s security and trustworthiness.
