Reviewer 1 Report (New Reviewer)
The authors present aFilter-based and Parallel Unknown Tag Identification Protocol in Open RFID Systems. The topic is interesting but the presentation needs improvements.
A careful proofreading is requested.
The abstract must be reformulated, the beginning must be removed, in my opinion the abstract starts at line 9, “this paper proposes...”
I did not understand the section number, why the first section is 0 and not 1? I suggest beginning with 1 for the introduction.
Section 2 must be improved with more information.
The sentence in lines 129-130 "The IDs of all known tags (including missing tags) are already stored in the back-end database of the server, but all IDs and M unknown tags are unavailable in the server" is not clear and must be reformulated.
In section 3, I suggest using flowcharts in order to help the reader.
It would be interesting to summarize the results and comparison with other methods in a Table in section 5.
Some references must be actualized or withdrawn, e.g, 40 to 42.

Reviewer 2 Report (New Reviewer)
The following are the review comments-
1. In the manuscript, authors have written "As shown in Fig. ??, our protocol.....", write down the Fig. .......
2. Authors must cite the mathematical equations.
3. Authors must compare the proposed technique with the exiting techniques.
4. There are some typos and grammatical errors.
5. Improve the picture quality of figures 6 and 7.
6. Abstract should be more effective.

Round 2
Reviewer 1 Report (New Reviewer)
All my comments were attended, in my opinion the paper was improved and now suitable for publication.
This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.
Round 1
Reviewer 1 Report
The paper entitled "A Filter-based and Parallel Unknown Tag Identification Protocol in open RFID systems" investigates the problem of unknown tag identification in open RFID systems and proposes a novel deterministic tag identification protocol called filter-based and parallel unknown tag identification (FPUI) protocol.
The manuscript is well written. The authors presented the problem and proposed a solution. They explained the procedure thoroughly and documented their results.
Nevertheless, the manuscript needs minor proofreading. For example:
Unknown tag identification plays a pivotal role in applications, but it is far from “being” thoroughly investigated. – line 6
“these” known tags – line 36
has better performance “than” the existing – line 80
WP [22] constructs a composite-line 96, the authors must be named
CFUI [26] “utilizes” coded filtering vector technique-line 110, and the authors must be named
etc.
The acronym must be explained before its first use.
Reviewer 2 Report
The writing should be improved. This totally affected the delivery of some sections. Some sections in the introduction need some clarification.
