Abstract: Embodiments of the invention involve using biometric templates to wirelessly authenticate individuals. In one embodiment, a mobile device may generate a first biometric template and a first public value from a first biometric sample of a user and generate a first cryptographic key by passing the first biometric template to a fuzzy extractor's generate function. An access device may generate a second biometric template from a second biometric sample of the user, generate a second secret cryptographic key by passing the second biometric template and the first public value to the fuzzy extractor's reproduce function, encrypt the second biometric template with the second secret cryptographic key, and broadcast the encrypted template to a plurality of nearby mobile devices including the mobile device. If the mobile device is able to decrypt the encrypted template with the first cryptographic key, the access device can associate the user with the mobile device.

Abstract: A funiary urn is disclosed. The urn includes a pedestal, a canister and a cap. The pedestal is attached to the canister by a bolt and a nut having an axially extended nut shank of non-circular cross-sectional shape for engaging mating apertures in the pedestal and in the canister. A gasket compressed between the inner canister surface and the nut top provides a seal inhibiting gas flow into or out of the canister at the attachment opening. When the cap is assembled to the canister, an inwardly embossed cap lip extends continuously around the cap at a locus spaced above the cap edge so as to engage the canister top edge and form a seal inhibiting gas flow. The cap is drawn tightly into its sealed position by an arrangement of detents and detent-accepting grooves.
