Merging and unmerging entity representations via resolver trees

A digital security system, comprising:

• one or more processors;
• and
• memory storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• identifying a first resolver tree comprising one or more first nodes storing first data associated with a first entity;
• identifying a second resolver tree comprising one or more second nodes storing second data associated with a second entity;
• determining that the first entity and the second entity are likely a same entity, by:
• generating a similarity score based on the first data and the second data;
• and
• determining that the similarity score is equal to or above a threshold;
• performing, based on determining that the first entity and the second entity are likely the same entity, a merge operation to add the one or more second nodes of the second resolver tree to the first resolver tree, wherein the merge operation is associated with a merge identifier;
• adding a merge node to the first resolver tree, wherein the merge node indicates the merge identifier;
• and
• tagging the one or more second nodes with the merge identifier in the first resolver tree.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors associated with a digital security system, cause the one or more processors to perform operations comprising:

• identifying a first resolver tree comprising one or more first nodes storing first data associated with a first entity;
• identifying a second resolver tree comprising one or more second nodes storing second data associated with a second entity;
• determining that the first entity and the second entity are likely a same entity, by:
• generating a similarity score based on the first data and the second data;
• and
• determining that the similarity score is equal to or above a threshold;
• performing, based on determining that the first entity and the second entity are likely the same entity, a merge operation to add the one or more second nodes of the second resolver tree to the first resolver tree, wherein the merge operation is associated with a merge identifier;
• adding a merge node to the first resolver tree, wherein the merge node indicates the merge identifier;
• and
• tagging the one or more second nodes with the merge identifier in the first resolver tree.
