Abstract: To synchronize data stored by a first device (e.g., a client system) with data stored by a second device (e.g., a server system), the first device encodes a first set of ordered data identifiers, stored in memory of the first device, to produce an encoded value, wherein the first set of ordered data identifiers is bound in accordance with a range indicator, and transmits the encoded value and the range indicator to the second device. The first device subsequently receives from the second device a remedial set of ordered data identifiers stored in memory of the second device when the encoded value does not match a corresponding value determined by the second device, wherein the remedial set of ordered data identifiers is also bound in accordance with the range indicator.
