Ginlo Business 與 Badges - Secure Badging & GPS 使用情況與統計

Badges provides true end-to-end security for Privacy and Anonymity. Claiming compliance with NIST SP800-56 rev3 C(1e,2s) and HKDF (RFC5869) standards and using AES128, SHA256, ECDH128, ECDSA256, Linkable Ring Signatures. Badges allows you to create cryptographic Digital Badges, where members are added over Bluetooth (physical pairing for key provisioning) and Messages, images, classifieds and GPS points are shared with end-to-end security through internet. Access Control: Badges allows you to cryptographically verify that members are granted access to the same Badges then you , without revealing your identity. In addition, Badges owner can distribute cryptographic Vouchers to their Members. Physical pairing with members over bluetooth: Because keys provisioning and keys exchange over the internet (even using https) remains a critical security issue, Badges propose to add members to Badges using Bluetooth thanks to physical and proximity pairing. This ensures no man in the middle attack is possible, and also guarantees non-repudiation of members. This also ensures that People in your Badge are in most cases closely related to you. Anonymity in Messenger, Classifieds and GPS: Badges uses novel Linkable Ring Signatures (LRS) over elliptic curve (P-256) to provide anonymity of members. The messages, images, classifieds and GPS points sent, and the voucher are End-to-End encrypted and cryptographically ensured Anonymous using so called LRS. Anonymous Badges properties: When creating a Badge, you can select whether you are the only one allowed to add members to this Badge or if any other Badge member can add new members to this Badge. In addition, you can select whether you are the only one allowed to send message, image and classifieds to the Badge, or if every member of the Badge is allowed to do so. This is particularly useful when you need to create professional Digital Badges Badging functionality: Each Badge can be used to allow people entering events, accessing services with voucher (e.g. private club), attest of privileges given by others, or prove ownership of a badge. Voucher functionality: Badges owners can distribute cryptographic vouchers. Cloud based: Badges is automatically synchronised on all your devices running under the same icloud account using iCloud keychain and iCloud drive. You can start a discussion on your iPhone, then continue it on your iPad, seamlessly. Thanks to End-to-End security, all messages, images, classifieds and GPS points can be securely stored outside of your devices, in cloud Servers. This greatly minimise the storage consumption on your device while providing easy access to any of your device. The messages, classifieds and GPS points of Badges that are not used for more than 3 weeks are automatically deleted.
