A digital component deduplication system for generating packetized data with encryption tokens for transmittal over one or more packetized networks, comprising: a keyed database storing keyed data, with each item of keyed data representing a particular digital component; a packetized data search engine that searches packetized data received from a first client device to determine that an encryption token is included with the packetized data, the encryption token comprising keyed data representing a first digital component, wherein the packetized data search engine searches the keyed database to identify contents, in the keyed database, of one or more entries that includes the keyed data representing the first digital component; a logic execution server that executes data logic to generate, based on the contents of the one or more entries that include the keyed data representing the first digital component, a list of candidate digital components; a registration interface that determines that a candidate digital component of the list is associated with a data interface for requesting an eligibility value from a second client device associated with the candidate digital component; and a security server that generates, using the data interface, additional packetized data comprising i) a request for the eligibility value from the second client device, and ii) the encryption token, wherein the logic execution server, in response to receiving the eligibility value of the request, designates, from the list of the candidate digital components, a second digital component for transmitting to the first client device, and wherein the second digital component is different than the first digital component. a keyed database storing keyed data, with each item of keyed data representing a particular digital component; a packetized data search engine that searches packetized data received from a first client device to determine that an encryption token is included with the packetized data, the encryption token comprising keyed data representing a first digital component, wherein the packetized data search engine searches the keyed database to identify contents, in the keyed database, of one or more entries that includes the keyed data representing the first digital component; a logic execution server that executes data logic to generate, based on the contents of the one or more entries that include the keyed data representing the first digital component, a list of candidate digital components; a registration interface that determines that a candidate digital component of the list is associated with a data interface for requesting an eligibility value from a second client device associated with the candidate digital component; and a security server that generates, using the data interface, additional packetized data comprising i) a request for the eligibility value from the second client device, and ii) the encryption token, wherein the logic execution server, in response to receiving the eligibility value of the request, designates, from the list of the candidate digital components, a second digital component for transmitting to the first client device, and wherein the second digital component is different than the first digital component.
