A rights-based system is described in which vouchers are employed for creating, managing, distributing, and redeeming rights in digital contexts. A voucher is a digital, possession-based rights representation. An authorization component of the system validates the vouchers and issues corresponding tokens. Access to digital resources is provided in response to presentation of the tokens which are validated by matching voucher refresh values to corresponding values maintained by the system. New refresh values are generated and inserted in the vouchers each time they are redeemed.

The rights-based system of claim 1, wherein each of the system components has one or more network addresses associated therewith and is configured to communicate with one or more of the other system components using Hyper-Text Transfer Protocol (HTTP) requests and responses directed to the network addresses associated with the one or more other system components. 3. The rights-based system of claim 1, wherein at least some of the vouchers also include a signed component for verifying the validity of the corresponding voucher, the signed component not being modifiable. 4. The rights-based system of claim 1, wherein at least some of the vouchers are not transferable, the authorization component being further configured to authenticate owners of the at least some of the vouchers. 5. The rights-based system of claim 1, wherein at least some of the vouchers include strings of text representing descriptive information regarding the corresponding voucher. 6. The rights-based system of claim 1, wherein the mint component is further configured to generate new vouchers and to request initial refresh values for the new vouchers from another one of the system components. 7. The rights-based system of claim 6, wherein the mint component is configured to generate one or more of the new vouchers only after validation of an existing one of the vouchers. 8. The rights-based system of claim 6, wherein the mint component is further configured to generate voucher templates from which the new vouchers are generated. 9. The rights-based system of claim 1, wherein the escrow component is configured to execute secure trades of the vouchers. 10. The rights-based system of claim 1, wherein at least some of the vouchers are configured to control access to others of the vouchers. 11. A computer-implemented method, comprising: using one or more computing devices, issuing first, second, and third vouchers, each of the vouchers being a digital possession-based rights representation, the second and third vouchers each having encoded therein a corresponding refresh value and a corresponding sequence number, the refresh value being a pseudo-random value, the third voucher representing multiple different but related access rights for a corresponding digital resource, the first voucher being configured to enable redemption of a corresponding right by anyone having a copy of the first voucher and without requiring submission of corresponding user credentials, the second voucher being configured to enable redemption of a corresponding right by only a single holder but without requiring submission of corresponding user credentials, and the third voucher being configured to require submission of corresponding user credentials to enable redemption of the corresponding rights;using one or more computing devices, validating the first voucher;using the one or more computing devices, issuing a first token corresponding to the first voucher in response to validation of the first voucher, the first token being configured to enable redemption of the right corresponding to the first voucher;using the one or more computing devices, redeeming the right corresponding to the first voucher in response to presentation of the first token;using the one or more computing devices, validating the second voucher by matching the corresponding refresh value to a corresponding most recent value stored separately from the second voucher as identified with reference to the corresponding sequence number;using the one or more computing devices, issuing a second token corresponding to the second voucher in response to validation of the second voucher, the second token being configured to enable redemption of the right corresponding to the second voucher;using the one or more computing devices, generating a new refresh value for the second voucher;using the one or more computing devices, inserting the new refresh value in the second voucher;using the one or more computing devices, updating the most recent value for the second voucher to match the new refresh value for the second voucher;using the one or more computing devices, incrementing the sequence number encoded in the second voucher;using the one or more computing devices, redeeming the right corresponding to the second voucher in response to presentation of the second token;using the one or more computing devices, determining that the user credentials submitted in conjunction with presentation of the third voucher correspond to the third voucher;using the one or more computing devices, validating the third voucher by matching the corresponding refresh value to a corresponding most recent value stored separately from the third voucher as identified with reference to the corresponding sequence number;using the one or more computing devices, issuing a third token corresponding to the third voucher in response to validation of the third voucher, the third token being configured to enable access to the digital resource in accordance with a subset of fewer than all of the multiple access rights;using the one or more computing devices, generating a new refresh value for the third voucher;using the one or more computing devices, inserting the new refresh value in the third voucher;using the one or more computing devices, updating the most recent value for the third voucher to match the new refresh value for the third voucher;using the one or more computing devices, incrementing the sequence number encoded in the third voucher; andusing the one or more computing devices, providing access to the digital resource according to the subset of the multiple access rights in response to presentation of the third token. 12.
