 I,
Michael Goldberg, certify that:
 
 1. I have
reviewed this Annual Report on Form 10-Q of IDO Security Inc. for the quarter
ended March 31, 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.
