The Small Arms Survey is a global centre of excellence whose mandate is to generate impartial, evidence-based, and policy-relevant knowledge on all aspects of small arms and armed violence. It is the principal international source of expertise, information, and analysis on small arms and armed violence issues, and acts as a resource for governments, policymakers, researchers, and civil society. It is located in Geneva, Switzerland, and is a project of the Graduate Institute of Inter- national and Development Studies. Accurately documenting and identifying weapons and ammunition is paramount to telling a story. Accurately documenting and identifying weapons and ammunition is paramount to telling a story. Nonetheless, it can be a challenging task. The Weapons Identification and Reporting App is specifically designed to help practitioners, researchers, and journalists to accurately report on small arms, light weapons, and ammunition that they come across in the course of their work. The app guides users to take photos of materiel in a way that will facilitate the identification process by ensuring that the relevant information is collected (including markings and distinctive physical features), offers secure storage space for photos taken or received by users, and allows for geotagging these pictures. Once the information is entered into the app, the user can choose to send a simple request to Small Arms Survey experts who can provide timely identification of the weapon and/or ammunition. The user can also choose to simply use the app as a way to organize their files and retrieve them later. If you have any questions or suggestions for improvements, please get in touch through the "Send Feedback" link in the app settings.

Self is the privacy-first way to prove you're human and verify who you are online (or give your agent a secure identity), without handing over your personal data. Trusted by Google, Opera, and 15M+ users. Verify your real-world identity once using a biometric passport, biometric national ID cards, Aadhaar, or any other supported identity document. Once registered, you can prove the specific attributes services require, such as your humanity, age, or nationality, without ever disclosing the underlying document or your personal information. Key Features: PROOF OF HUMAN: Prove you're a real person rather than an automated or duplicate account. AGE VERIFICATION: Confirm you're over 18 (or any age threshold) without revealing your birthday. Built for social apps, marketplaces, and age-gated services. PRE-KYC: Verify your eligibility (age, country of residence, sanctions, etc.) before any KYC process, only sharing your personal information with companies and institutions once necessary. AGENT ID: Delegate your identity credentials to your autonomous agent, unlocking broader utility and access across the internet. PRIVACY BY DESIGN: Self is using the latest zero-knowledge technology, fully audited by the world’s best security experts. All data is stored locally on the user’s device — never on any servers. When a user verifies their identity, a verifiable credential is created and saved securely in the app. There’s no cloud storage, no centralized database, and no way for anyone - including Self - to access the data without the user's consent. "We’re committed to ensuring developers can build faster with reduced friction while maintaining industry‑leading security standards," said Rich Widmann, Google. "Integrating Self allows us to further this mission with frontier zero‑knowledge solutions." Why Self Defend against bots and duplicate identities Meet age and compliance requirements without surrendering personal information Carry one verified identity across the apps you use, instead of re-uploading documents at every sign-up Help establish a global standard for verified identity that keeps people, not platforms, in control of their data
