RULE 13A-14(A) / 15D-14(A) CERTIFICATION





I,
Michael Goldberg, certify that:





1.
     I have reviewed this Quarterly Report on Form 10-Q of
IDO Security Inc. for the quarter ended June 30, 2009.





2.
     Based on my knowledge, this annual report does not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements made, in light of the circumstances under which
such statements were made, not misleading with respect to the period covered by
this report;





3.
     Based on my knowledge, the financial statements, and
other financial information included in this report, fairly present in all
material respects the financial condition, results of operations and cash flows
of the registrant as of, and for, the period presented in
this  report;





4.
     I am responsible for establishing and maintaining
disclosure controls and procedures (as defined in Exchange Act
Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant and I have:




a)      designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be designed under my
supervision, to ensure that material information relating to the registrant,
including its consolidated subsidiaries, is made known to me by others within
those entities, particularly during the period in which this report is being
prepared;




b)      designed such internal control over financial
reporting, or caused such internal control over financial reporting to be
designed under my supervision, to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted accounting
principles;




c)      evaluated the effectiveness of the registrant's
disclosure controls and procedures and presented in this report my conclusions
about the effectiveness of the disclosure controls and procedures, as of the end
of the period covered by this report based on such evaluation; and




d)      disclosed in this report any change in the
registrant’s internal control over financial reporting that occurred during the
registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter
in the case of an annual report) that has materially affected, or is reasonably
likely to materially affect, the registrant’s internal control over financial
reporting;





5. I have disclosed, based on my most recent
evaluation of internal control over financial reporting, to the registrant's
auditors and the audit committee of the registrant's board of directors (or
persons fulfilling the equivalent function):




a)      All significant deficiencies and material weaknesses
in the design or operation of internal control over financial reporting which
are reasonably likely to adversely affect the registrant's ability to record,
process, summarize and report financial information; and




b)      Any fraud, whether or not material, that involves
management or other employees who have a significant role in the registrant's
internal control over financial reporting.
