A device may generate a file containing such information, and a file name of the file may exclude identifying information for the content provider, such as a Uniform Resource Locator (“URL”) or domain name associated with the content provider. The device may generate a first mapping between the file name and the content provider, and may record the first mapping to a ledger system. The device may maintain a second mapping of an identifier of a portion of the ledger system, in which the first mapping was recorded, to the content provider, and may use this second mapping to retrieve the information from the file upon an authorized request. ## Claims ### Claim 1 A device, comprising: one or more processors configured to: receive information from a particular source that is associated with a first identifier; associate a file storing the received information with a second identifier; provide mapping information, associating the first and second identifiers, to a ledger system; receive, after providing the mapping information to the ledger system, a request that includes the first identifier; retrieve, based on the first identifier included in the request, the mapping information from the ledger system; utilize the retrieved mapping information to identify the file; and output, in response to the request, some or all of the information stored in the identified file. ### Claim 2 (depends on 1) The device of claim 1, wherein the first identifier includes at least one of: a Uniform Resource Locator (“URL”) associated with the particular source, or a domain name associated with the particular source. ### Claim 3 (depends on 1) The device of claim 1, wherein the device forgoes maintaining the mapping information in a local storage device after providing the mapping information to the ledger system. ### Claim 4 (depends on 3) The device of claim 3, wherein the device further forgoes maintaining the mapping information in the local storage device after utilizing the mapping information to identify the file. ### Claim 5 (depends on 1) The device of claim 1, wherein the one or more processors are further configured to: perform a cryptographic hash operation on the first identifier, wherein the mapping information includes decryption information associated with the cryptographic hash operation. ### Claim 6 (depends on 1) The device of claim 1, wherein the particular source is a first source, wherein the file is a first file, and wherein the information received from the first source is first information, wherein the one or more processors are further configured to: receive, from a second source, second information, wherein the second source is associated with a third identifier; and generate a second file storing the second information, wherein generating the second file includes generating a second file name for the second file, the second file name including the third identifier. ### Claim 7 (depends on 1) The device of claim 1, wherein the one or more processors are further configured to: maintain information indicating a particular record, associated with the ledger system, in which the mapping information is stored, wherein retrieving the mapping information includes retrieving the mapping information based on the maintained information indicating the particular record associated with the ledger system. ### Claim 8 A non-transitory computer-readable medium, storing a plurality of processor-executable instructions to: receive information from a particular source that is associated with a first identifier; associate a file storing the received information with a second identifier; provide mapping information, associating the first and second identifiers, to a ledger system; receive, after providing the mapping information to the ledger system, a request that includes the first identifier; retrieve, based on the first identifier included in the request, the mapping information from the ledger system; utilize the retrieved mapping information to identify the file; and output, in response to the request, some or all of the information stored in the identified file. ### Claim 9 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the first identifier includes at least one of: a Uniform Resource Locator (“URL”) associated with the particular source, or a domain name associated with the particular source. ### Claim 10 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the processor-executable instructions further include processor-executable instructions to forgo maintaining the mapping information in a local storage device after providing the mapping information to the ledger system. ### Claim 11 (depends on 10) The non-transitory computer-readable medium of claim 10, wherein the processor-executable instructions further include processor-executable instructions to forgo maintaining the mapping information in the local storage device after utilizing the mapping information to identify the file. ### Claim 12 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the plurality of processor-executable instructions further include processor-executable instructions to: perform a cryptographic hash operation on the first identifier, wherein the mapping information includes decryption information associated with the cryptographic hash operation. ### Claim 13 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the particular source is a first source, wherein the file is a first file, and wherein the information received from the first source is first information, wherein the plurality of processor-executable instructions further include processor-executable instructions to: receive, from a second source, second information, wherein the second source is associated with a third identifier; and generate a second file storing the second information, wherein generating the second file includes generating a second file name for the second file, the second file name including the third identifier. ### Claim 14 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the plurality of processor-executable instructions further include processor-executable instructions to: maintain information indicating a particular record, associated with the ledger system, in which the mapping information is stored, wherein retrieving the mapping information includes retrieving the mapping information based on the maintained information indicating the particular record associated with the ledger system. ### Claim 15 A method, comprising: receiving information from a particular source that is associated with a first identifier; associating a file storing the received information with a second identifier; providing mapping information, associating the first and second identifiers, to a ledger system; receiving, after providing the mapping information to the ledger system, a request that includes the first identifier; retrieving, based on the first identifier included in the request, the mapping information from the ledger system; utilizing the retrieved mapping information to identify the file; and outputting, in response to the request, some or all of the information stored in the identified file. ### Claim 16 (depends on 15) The method of claim 15, wherein the first identifier includes at least one of: a Uniform Resource Locator (“URL”) associated with the particular source, or a domain name associated with the particular source. ### Claim 17 (depends on 15) The method of claim 15, further comprising: forgoing maintaining the mapping information in a local storage device after providing the mapping information to the ledger system; and forgoing maintaining the mapping information in the local storage device after utilizing the mapping information to identify the file. ### Claim 18 (depends on 15) The method of claim 15, the method further comprising: performing a cryptographic hash operation on the first identifier, wherein the mapping information includes decryption information associated with the cryptographic hash operation. ### Claim 19 (depends on 15) The method of claim 15, wherein the particular source is a first source, wherein the file is a first file, and wherein the information received from the first source is first information, the method further comprising: receiving, from a second source, second information, wherein the second source is associated with a third identifier;
